Link between Fokker-Planck equation and Feynman-Kac formula

According to the Feynman-Kac formula, we know the solution of the partial differential equation: $${\frac {\partial u}{\partial t}}(x,t)+\mu (x,t){\frac {\partial u}{\partial x}}(x,t)+{\tfrac {1}{2}}\ …

Proof of the link between the Fokker–Planck equation and SDE?

I know the link between the Fokker–Planck equation and SDE given by the Feynman-Kac theorem is as follow: $$d X_{t}=\mu\left(X_{t}, t\right) d t+\sigma\left(X_{t}, t\right) d W_{t}$$ $$\frac{\partial} …

Solving Fokker–Planck equation

Consider the Fokker–Planck equation: $${\displaystyle {\frac {\partial }{\partial t}}p(x,t)=-{\frac {\partial }{\partial x}}\left[\mu (x,t)p(x,t)\right]+{\frac {\partial ^{2}}{\partial x^{2}}}\left[D( …
