I am often asked in emails how to go about learning the necessary mathematics for getting a job in quantitative finance or data science if it isn't possible to head to university. This article is a response to such emails. I want to discuss how you can become a mathematical autodidact using nothing but a range of relatively reasonably priced textbooks and resources on the internet. While it is far from easy to sustain the necessary effort to achieve such a task outside of a formal setting, it is possible with the resources both paid and free that are now available. We'll begin by discussing the reasons for wanting to learn advanced mathematics, be it career-driven, to gain entrance into formal education or even as a hobby. I will then present the different study materials available for the equivalent of an undergraduate course, how to access them and how to make the best use of them.
You must give it serious consideration and make sure that the payoff financial or otherwise from study will be worth the serious effort required. These days it is possible to study from a mixture of freely available video lectures, lecture notes and textbooks. There are those who learn better from watching videos and making notes, while others enjoy working methodically through a textbook.
I've listed what I consider to be the most useful resources below. At the undergraduate level, I am a big fan of the Springer Undergraduate Mathematics Series of textbooks, which cover pretty much every major course you will find on a top-tier mathematics undergraduate degree in the UK. I will go into detail regarding choices of books for specific modules below.
I've also found the Schaum's Outlines series of books to be extremely helpful, particularly for those who like to learn by answering questions. While they don't go into the detail that others might particularly the SUMS books above , they do help consolidate the basics by working through a lot of questions.
I highly recommend them if you've not seen any of the material before. Many Universities provide publicly accessible course pages that contain freely available lecture notes, often in PDF format, typeset in LaTeX or similar.
Where appropriate, I've listed freely available lecture notes for particular courses. However, I prefer to recommend textbooks as they tend to cover a wider set of material.
They aren't "cherry picking" material in a way that a lecturer will have to do so in order to fit the material into semester-length courses. Despite this issue, there are some extremely good lecture notes available online.
The rise of Massive Open Online Courses MOOCs has fundamentally changed the way students now interact with lecturers, whether they are enrolled on a particular course or not. Some MOOCs are free, while others charge. On the whole, I've found MOOCs to be a great mechanism for learning as they are similar to how students learn at University, in a lecture setting. They provide the added benefits of being able to pause videos, rewind them, interaction with lecturers on online portals as well as easy access to supplementary materials.
Some have suggested that the quality of MOOCs is not as good as that which can be found in a University setting, but I disagree with this. There are some extremely good MOOCs available in data science, machine learning and quantitative finance. However, I have found there to be a lack of more fundamental courses and as such you'll see me recommending textbooks for the majority of the courses listed here.
At this stage of your mathematical career you will be familiar with the basics of differential and integral calculus, trigonometric identities, perhaps some elementary linear algebra and possibly some elementary group theory, gained from highschool or through self-study.
The methods for teaching mathematics at highschool level are largely mechanical in nature and do not require a deep level of thinking. At University, mathematics becomes largely about formal systems of axioms and an emphasis on formal proofs. This means that ones thinking is shifted from mechanical solution of problems, utilising a "toolbox" of techniques, towards deep thought about disparate areas of mathematics that can be linked in order to prove results.
It is the fundamental difference between highschool mathematics and undergraduate mathematics. In fact, it is this particular mode of thinking that makes mathematics such a highly sought after degree in the quantitative finance world.
Self-study of university level mathematics is not an easy task, by any means.
It requires a substantial level of discipline and effort to not only make the cognitive shift into "theorem and proof" mathematics, but also to do this as a full autodidact. For those of you who are unable or unwilling to carry out formal study in a university setting and wish to tackle a full syllabus of undergraduate mathematics, I have created a comprehensive study plan below to take you from high school level mathematics to the equivalent of a four-year Masters in Mathematics undergraduate course.
I have presented it in a year-by-year, module-by-module format with plenty of further reference materials to study at your own pace.
Since a degree course is often tailored to the desires of the individual in the latter two years, I have created a syllabus which broadly reflects the topics that a prospective quant should know. However, you can obviously add your own choices for your own particular situation. To this end, I have made suggestions where appropriate. This article will concentrate on Year 1 of a degree program, with subsequent articles each covering an entire year.
The courses found in a first year largely reflect this transition, whereby the following core topics are emphasised:. Most top-tier UK undergraduate courses have a "Foundations" module of some description.
The goal of the course is to provide you with a detailed overview of the nature of university mathematics, including the notions of proof such as proof by induction and proof by contradiction , the concept of a map or function , as well as the differing types such as the injection , surjection and bijection. In addition to these topics, the concept of a set is formally outlined, as well as the induced structure on such sets by operations , leading to the concept of groups. These core topics and ideas will prepare you for the deeper topics of analysis, linear algebra and differential equations that form the remainder of a first year undergraduate syllabus.
Self-study of mathematical foundations can be challenging, as it is often the first time you will have seen the concept of a proof. It can be bewildering at the beginning to understand how proofs can be constructed, but as with everything else in life, it is possible to learn how to structure proofs through a lot of reading and practice.
Perhaps the best way to learn mathematical foundations is through "bedside reading", or perhaps more rigourous study, of some of the better known textbooks. I myself learnt from the following two books listed under Study Materials below. I can highly recommend them as they certainly provide a good taste as to what university mathematics is all about.
Real Analysis is a staple course in first year undergraduate mathematics. It is an extremely important topic, especially for quants, as it forms the basis for later courses in stochastic calculus and partial differential equations. The subject is primarily about real numbers and functions between sets of real numbers.
The main topics discussed include sequences , series , convergence , limits , calculus and continuity. The primary benefit of studying real analysis is that it provides a gentle introduction to proofs, using examples that aren't too unfamiliar from A-Level highschool equivalent mathematics.
In this way, real analysis courses teach not only the "mindset" of forming proofs, but also introduce more abstract concepts such as "proper" definitions of infinity , axioms such as the axiom of completeness and some good experience manipulating continuous functions and their derivatives.
In order to learn Real Analysis by yourself, I would suggest taking a look at the textbook Numbers and Functions: Steps into Analysis listed below. I used this to learn Real Analysis when I was at university and I found it extremely helpful.
The book teaches you by getting you to carry out a large number of questions, rather than throwing a huge amount of text at you. In this way you learn by doing.
In addition to that book, I have listed a few others that are helpful. The video quality is not great, but the content is extremely good. Linear Algebra is one of the most important, if not the most important, subjects to learn for a prospective quant or data scientist. In an abstract sense Linear Algebra is about the study of linear maps between vector spaces.
It teaches us that in certain cases linear maps and matrices are actually equivalent. This latter result makes it extremely useful when dealing with matrix equations, of which there are many within quantitative finance and data science.
The majority of statistical machine learning methods are based on the principles of linear algebra and calculus, as are many quantitative finance theories, such as the covariance matrix and the capital asset pricing model. Hence, it is imperative for prospective quants to learn it well. Thankfully, Linear Algebra has such a wide applicability in mathematics, physics, engineering and science in general, that there are many great resources available for learning it.
In addition to his textbook, you can also find a set of video lectures presented by him on MIT Open Courseware.
The subject of differential equations permeates wide areas of quantitative finance. They are an extremely important subject for a prospective quant to learn, as stochastic differential equations play a large part in options pricing theory.
Formally, a differential equation is a relationship between a function and its derivatives. Informally, they are equations, which describe how rates of change of the function, with respect to some other quantity, affect the function itself. An ODE is a differential equation where the underlying function has one independent variable.
For instance, an ODE could represent the rate of change of population growth as a function of the population level itself. As a quant, it is necessary to understand the basics of ODEs and how to solve them. Since the more complicated partial differential equations PDE and stochastic differential, equations SDE are widely found in quantitative analysis and trading, understanding the solution of the more simpler ODEs helps with understanding solutions of these problems.
Some ODEs can be solved analytically , that is, with a closed-form solution, using elementary functions. However, the solution to many ODEs can only be written as a series or integral relationship. ODEs can be solved "numerically", on the computer, using approximate methods. A large part of quantitative finance involves numerically solving differential equations in this manner.
There is no lack of study materials available for ODEs as they are a staple of the first year undergraduate mathematics program. I used the book written by my lecturer at University, and I found it to be approachable for a first year undergraduate see Robinson, below. Geometry is one of the most fundamental areas of mathematics. It is absolutely essential for many areas of deeper mathematics, including those related to quantitative finance.
Many undergraduate courses introduce Euclidean geometry to students in their first year, and it is also an appropriate place to start for the autodidact.
The primary setting is often Euclidean Geometry in three-dimensions, namely the geometry of "everyday life". You will learn a lot about constructing proofs from studying geometry, particularly with regards to projective geometry in the plane and geometry of the sphere.
In highschool or at GCSE! Euclidean Geometry eventually leads on to more general geometries such as Spherical Geometry or Hyperbolic Geometry, where familiar results from Euclidean Geometry are shown not to hold. In addition, and perhaps more relevant to the quant, having a good understanding of trigonometry is essential for later courses such as Fourier Analysis, which plays a substantial role in signals analysis and time series analysis.
Geometry is a tricky subject to introduce as it is extremely broad and covers such a diverse area of mathematics. However, I have found the following book, part of the Springer Undergraduate Mathematics Series, to be very helpful:. Groups are one of the most important algebraic structures found in mathematics. They provide the basis for studying more complex structures such as rings, fields, vector spaces which we mentioned above in Linear Algebra.
They are also strongly related to the idea of mathematical symmetry. While it might be considered that groups are more of a "pure mathematics" topic, and thus are less applied, this is actually not the case.
