Mondays, 1:25-3:15pm, Warren Weaver Hall 512
Instructor: Miranda Holmes-Cerfon
Office Hours: (tentatively) Thursdays 4-6pm, WWH 1107

Prerequisites: Basic Probability (or equivalent masters-level probability course), and good upper level undergraduate or beginning graduate knowledge of linear algebra, ODEs, PDEs, and analysis.

Description: This course will introduce the major topics in stochastic analysis from an applied mathematics perspective. Topics to be covered include Markov chains, stochastic processes, stochastic differential equations, numerical algorithms. It will pay particular attention to the connection between stochastic processes and PDEs, as well as to physical principles and applications. The class will attempt to strike a balance between rigour and heuristic arguments: it will assume that students have some familiarity with measure theory and analysis and will make occasional reference to these, but many results will be derived through other arguments. The target audience is PhD students in applied mathematics, who need to become familiar with the tools or use them in their research.

The course will be divided roughly into two parts, taking roughly an equal amount of time: Part I will focus on stochastic processes, and Part II will focus on stochastic calculus.

Homework will be a critical part of the course. Lectures will mostly be theory, and examples or extensions will be assigned as homework problems. You must do these if you want to learn something from the course. Homework will require some computing, preferably in Python or Matlab. Students without programming experience will have to put in extra effort in the first few weeks.


There are three textbooks that are not required, but that are highly recommended:
  • G. A. Pavliotis, Stochastic Processes and Applications.
  • G. Grimmett and D. Stirzaker, Probability and Random Processes. (This is the textbook for Basic Probability)
  • C. Gardiner, Stochastic Methods: A Handbook for the Natural and Social Sciences.
You can download the first one for free from the Springer website if you are a member of NYU. It will also be available at the bookstore.
