MATHGA.1234001 Cryptocurrency And Blockchains: Mathematics And Technologies
1.5 Points, Thursdays, 7:109:00PM, Amir Sadr and Petter Kolm
Prerequisites: Multivariate calculus and calculusbased probability. Students should have completed Computing in Finance (MATHGA2401) or equivalent, have strong coding skills in Python, and working experience with the Python stack (numpy/pandas/scikitlearn).
Description: This halfsemester course examines the building technologies and concepts in distributed ledger technologies and the workings of crypto financial markets.
We begin by an overview of the traditional central banking system and the mechanics of central bank money and commercial bank lending as the two dominant mechanisms of money creation. We explore the current network of banking in traditional finance (TradFi) and its hierarchy of commercial banks, central banks, correspondent banks, settlement and clearing mechanism, and the instruments used to create and transmit money.
We cover the principles of private and public key cryptography and its usage in encryption, digital signature, and message authentication. Hash functions serve as oneway functions that play a prominent role in creating message digests and solving the cryptographic puzzle in proofofworkbased blockchains. We cover the main challenges of secure communication and typical attacks such as replay, maninthemiddle, Sybil attacks and the cryptographic techniques used to tackle them.
Next, we take a deepdive in the original Bitcoin whitepaper and show how the integration of cryptographic digital signatures, recursive blockchains, hashbased proofofwork consensus mechanism to solve the 51% attack, and doublespend problem gave rise to the pioneering Bitcoin blockchain.
The Ethereum blockchain and its smart contracts have given rise to a variety of distributed apps (dApps), prominent among them decentralized exchanges (DEX) using constant function demand curves for creating automatic marketmaking. We cover the mechanics of these markets and concepts of swapping, liquidity pairs, yield farming and the general landscape of decentralized finance (DeFi).
Blockchain data is public by design and there is a wealth of realtime and historical data. We discuss some of the data analysis and machine learning methods utilized to analyze this type of data.
Given that blockchain is a software protocol, it is important that students taking this course have strong coding skills in Python and working experience with the Python stack (numpy/pandas/scikitlearn).

MATHGA.2830001 Advanced Topics In Applied Math: Theory Of Deep Learning
3 Points, Thursdays, 3:205:05PM, Arthur Jacot

Prerequisites: Familiarity with the foundational mathematical tools of finance; basic understanding of the motivation for and the machinery of pricing models in the interestrate domain; programming skills; basic proficiency in Excel. Some product knowledge of interestrate products is helpful but not required.
Description: Armed with a foundation in bond math and the theory and implementation of interestrate models, many fixedincome quants are challenged to understand how these concepts and tools are deployed in the sales/trading environment. Often the economic content of a simple trade idea gets obscured by market jargon, especially in a competitive transactional environment. The class will focus on the practical workings of the fixedincome and ratesderivatives markets.The content is motivated by a representative set of realworld trading, investment, and hedging objectives. Each situation will be examined from the ground level; risk and reward attributes will be identified. This strategy will reinforce the link from underlying market views to the applicable product set and to the tools for managing the position. Common threads among products – structural or modelbased – will be emphasized. We plan on covering bonds, swaps, flow options, semiexotics, and some structured products.
This problemoriented holistic view is a productive way to understand the line from product creation to modeling, marketing, trading, and hedging. We hope to convey intuition about both the power and limitations of models. How do sellside practitioners manage the various constraints and imperfections in the context of changing market backdrops and customer demands?

Course Prerequisites: DSGA 1002 and DSGA 1014, or equivalent coursesCourse Description: This course provides rigorous tools for the mathematical analysis of statistical procedures in data science. Topics include hypothesis testing, confidence sets, regression, classification, and nonparametric statistics. We will focus both on classical asymptotic theory and on modern nonasymptotic techniques and theorems suitable for data science applications. Prerequisites: linear algebra, probability, comfort with mathematical proofs.

MATHGA.2901001 Essentials Of Probability
3 Points, Mondays, Wednesdays, 3:304:45PM, Eric Vanden Eijnden
Prerequisites: Calculus through partial derivatives and multiple integrals; no previous knowledge of probability is required.
Description: The course introduces the basic concepts and methods of probability.
Topics include: probability spaces, random variables, distributions, law of large numbers, central limit theorem, random walk, Markov chains and martingales in discrete time, and if time allows diffusion processes including Brownian motion.
Required text:
Probability and Random Processes, 3rd edition by G.Grimmett and D. Stirzaker, Oxford Press 2001 (Note: this is NOT the newer 4th edition).

MATHGA.2903001 Stochastic Calculus (2nd Half Of Semester)
3 Points, Mondays, 7:109:00PM, Alexey Kuptsov
Prerequisite: Multivariate calculus, linear algebra, and calculusbased probability.
Description: The goal of this halfsemester course is for students to develop an understanding of the techniques of stochastic processes and stochastic calculus as it is applied in financial applications. We begin by constructing the Brownian motion (BM) and the Ito integral, studying their properties. Then we turn to Ito’s lemma and Girsanov’s theorem, covering several practical applications. Towards the end of the course, we study the linkage between SDEs and PDEs through the FeynmanKac equation. It is important that students taking this course have good working knowledge of calculusbased probability. 
MATHGA.2911001 Probability Theory I
3 Points, Mondays, Wednesdays, 11:0012:15PM, Paul Bourgade
Prerequisites: A first course in probability, familiarity with Lebesgue integral, or MATHGA 2430 Real Variables as mandatory corequisite.
Description: First semester in an annual sequence of Probability Theory, aimed primarily for Ph.D. students. Topics include laws of large numbers, weak convergence, central limit theorems, conditional expectation, martingales and Markov chains.

MATHGA.3001001 Geophysical Fluid Dynamics
3 Points, Tuesdays, 9:0010:50AM, Olivier Pauluis
Description:
This course serves as an introduction to the fundamentals of geophysical fluid dynamics. No prior knowledge of fluid dynamics will be assumed, but the course will move quickly into the subtopic of rapidly rotating, stratified flows. Topics to be covered include (but are not limited to): the advective derivative, momentum conservation and continuity, the rotating NavierStokes equations and nondimensional parameters, equations of state and thermodynamics of Newtonian fluids, atmospheric and oceanic basic states, the fundamental balances (thermal wind, geostrophic and hydrostatic), the rotating shallow water model, vorticity and potential vorticity, inertiagravity waves, geostrophic adjustment, the quasigeostrophic approximation and other smallRossby number limits, Rossby waves, baroclinic and barotropic instabilities, Rayleigh and CharneyStern theorems, geostrophic turbulence. Students will be assigned biweekly homework assignments and some computer exercises, and will be expected to complete a final project. This course will be supplemented with outofclass instruction.
