B0320 - STOCHASTIC CALCULUS II

Academic Year 2024/2025

  • Teaching Mode: Traditional lectures
  • Campus: Bologna
  • Corso: Second cycle degree programme (LM) in Mathematics (cod. 5827)

Learning outcomes

At the end of the course, the student knows the fundamental ideas and tools of stochastic control theory in continuous time and its connections with the theory of parabolic and elliptic partial differential equations. The student can independently carry out further studies on stochastic dynamic optimization for a wide range of applications (Economics, Finance, Biology, Epidemiology, Engineering).

Course contents

Part I - Introduction to optimal control theory

Introduction to optimal control and dynamic optimization: Motivations and examples. Formulation of optimal control problems in  continuous time. Basic ideas and results of the dynamic programming method in the deterministic setting.

Part II - Stochastic optimal control

Bellman's optimality principle; Hamilton-Jacobi-Bellman equations: classical and viscosity solutions; some regularity results for HJB equations; verification theorems and transversality conditions. Applications to portfolio optimization.

Part III - Optimal stopping and singular stochastic control

Dynamic to programming equation and verification theorems. Applications American options and to irreversible investment problems.
