Recently developed courses

Stochastic Partial Differential Equations (Math 545, Illinois Tech)

This course aims to give a fair introduction to general theory of Stochastic Partial Differential Equations (SPDEs), and their applications to various areas of applied mathematics. Starting with simple examples of SPDEs, such as stochastic heat equation, the courses advances to general theory of existence, uniqueness and regularity of the solutions for a SPDEs (mainly parabolic). In the second part of the course, students will learn fundamentals of statistical analysis for stochastic processes with main focus on parameters estimation problems for parabolic SPDEs.

The course is designed for graduate students with general research interests in stochastic methods. Students are expected to have some basic knowledge of PDEs and stochastic calculus.

Course Plan:

1. Prelimenaries

- - Martingales, Stochastic Integral, Kolmogorov criterion, Gronwall and BDG inequalities
  - Some deterministic PDEs
  - Brownian Motion and Ito’s calculus in infinite dimensions

2. Examples of SPDEs based on applications

3. Stochastic Parabolic Equations

- - Heat equation and reaction-diffusion equations
  - Energy estimates in Sobolev spaces
  - Existence and uniqueness of the solutions
  - Regularity of the solutions

4. Numerical Solutions for SPDE

5. Statistical Inference for SPDEs

- - Statistical inference for stochastic ordinary differential equations
  - Statistical inference for diagonalizable SPDE
  - Statistical inference for non-diagonalizable SPDE

Quantitative Risk Management (Math 588, Illinois Tech)

The course covers the major concepts and ideas from the modern risk management . It builds upon general theory of risk measures and performance measures and addresses the current regulatory requirements for market participants.

Significant part of the course will be devoted to practical aspects of the risk management, including: working with real market data, implementing the theoretical concepts by developing Python libraries that perform a comprehensive risk analysis of portfolios of various financial instruments.

The course should be accessible to students with knowledgeable of general probability (Math 475) and elements of financial markets (Math 548 or Math 485).

Course Plan:

1. Basic concepts in risk management

- - History of risk management and contemporary regulatory framework
  - Modeling portfolio value and its change (basic concepts)
  - Value-at-risk, expected shortfall and other risk measures

2. Modeling portfolio value and its change

- - Empirical properties of financial data
  - Financial time series
  - Extreme value theory (optional)
  - Multivariate models and copulas

3. Theory of risk and performance measures

- - Coherent and convex risk measures
  - Performance measures
  - Aggregation and capital allocation

4. Applications to Market risk and Credit Risk

5. Central Clearing Counterparties (CCP)
