introduction

  • The classical Feynman-Kac formula states the connection between
    • linear parabolic partial differential equations (PDEs), like the heat equation, and
    • expectation of stochastic processes driven by Brownian motion
  • It gives then a method for solving linear PDEs by Monte Carlo simulations of random processes


memo

  • One possible source is the book of Brian Hall on quantum mechanics for mathematicians.
  • Another possibility is the series on functional analysis by Reed and Simon
  • Fokker–Planck equation
