Feynman kac theorem
The Feynman–Kac formula, named after Richard Feynman and Mark Kac, establishes a link between parabolic partial differential equations (PDEs) and stochastic processes. In 1947, when Kac and Feynman were both Cornell faculty, Kac attended a presentation of Feynman's and remarked that the two of them … See more A proof that the above formula is a solution of the differential equation is long, difficult and not presented here.

Web2. By applying the Feynman-Kac theorem. 3. By transforming the Black Scholes PDE into the heat equation, for which a solution is known. This is the original approach adopted by Black and Scholes [1]. 4. Through the Capital Asset Pricing Model (CAPM).

In contrast to the Feynman-Kac formula, equation (2.5) gives a stochastic differential equation which can in principle be (numerically) solved in a dynamic fashion to yield an

From the probabilistic point of view the theorem says that the distributions of certain functionals of stochastic processes can be derived with the help of PDE theory.
