Abstract:
The stationary Kolmogorov equation
with partially singular diffusion matrix and discontinuous drift coefficient is studied.
Sufficient conditions for the existence of a probabilistic solution are obtained.
Examples demonstrating the sharpness of these conditions are given.
Keywords:Kolmogorov equation, invariant measure of a diffusion process, Lyapunov function.
