WebDec 22, 2024 · The generator of this SDE is The Feynman-Kac formula in backwards formulation states that the function solves the PDE with terminal condition . The forward formulation states that solves the PDE with initial condition . On the level of PDEs, it is intuitive and easy to see how the forward and backward formulations interact, namely .
