Weak solutions to Kolmogorov-Fokker-Planck equations: regularity, existence and uniqueness
Pascal Auscher, Cyril Imbert, Lukas Niebel
We prove existence, uniqueness and regularity of weak solutions of Kolmogorov--Fokker--Planck equations with either local or non-local diffusion in the velocity variable and rough…

Fundamental solutions to Kolmogorov-Fokker-Planck equations with rough coefficients: existence, uniqueness, upper estimates
Pascal Auscher, Cyril Imbert, Lukas Niebel
We show the existence and uniqueness of fundamental solution operators to Kolmo\-gorov-Fokker-Planck equations with rough (measurable) coefficients and local or integral diffusion…
