Spatial regularity for a class of degenerate Kolmogorov equations

  title={Spatial regularity for a class of degenerate Kolmogorov equations},
  author={Francesca Anceschi},
We establish spatial a priori estimates for the solution u to a class of dilation invariant Kolmogorov equation, where u is assumed to only have a certain amount of regularity in the diffusion’s directions, i.e. x1, . . . , xm0 . The result is that u is also regular with respect to the remaining directions. The approach we propose is based on the commutators identities and allows us to obtain a Sobolev exponent that does not depend on the integrability assumption of the right-hand side. Lastly… 


A note on the weak regularity theory for degenerate Kolmogorov equations
The aim of this work is to prove a Harnack inequality and the Hölder continuity for weak solutions to the Kolmogorov equation L u = f with measurable coefficients, integrable lower order terms and
Hypoelliptic Regularity in Kinetic Equations
On the trend to global equilibrium in spatially inhomogeneous entropy-dissipating systems : The linear Fokker-Planck equation
In this interesting article the authors study the long-time behaviour of kinetic equations with a degenerate collision operator action only on the velocity variable v. The main result proves a decay
Global $L_p$ estimates for kinetic Kolmogorov-Fokker-Planck equations in nondivergence form
We study the degenerate Kolmogorov equations (also known as kinetic Fokker-Planck equations) in nondivergence form. The leading coefficients a are merely measurable in t and satisfy the vanishing
Variational methods for the kinetic Fokker-Planck equation
We develop a functional analytic approach to the study of the Kramers and kinetic Fokker-Planck equations which parallels the classical $H^1$ theory of uniformly elliptic equations. In particular, we

Consider a class of non-homogenous ultraparabolic differential equations with drift terms or lower order terms arising from some physical models, and we prove that weak solutions are Hölder
On a spatially inhomogeneous nonlinear Fokker-Planck equation: Cauchy problem and diffusion asymptotics
We investigate the Cauchy problem and the diffusion asymptotics for a spatially inhomogeneous kinetic model associated to a nonlinear Fokker-Planck operator. Its solution describes the density
Harnack inequality for kinetic Fokker-Planck equations with rough coefficients and application to the Landau equation
We extend the De Giorgi--Nash--Moser theory to a class of kinetic Fokker-Planck equations and deduce new results on the Landau-Coulomb equation. More precisely, we first study the H{o}lder regularity
Classical Fundamental Solution of the Cauchy Problem for Ultraparabolic Kolmogorov-Type Equations with Two Groups of Spatial Variables of Degeneration. I
We construct a classical fundamental solution of the Cauchy problem for the degenerate ultraparabolic Kolmogorov-type equation with two groups of spatial variables of degeneration. We also

that is, if u must be a C ~ function in every open set where Pu is a C ~ function. Necessary and sufficient conditions for P to be hypoelliptic have been known for quite some time when the
