Weighted ${L^p}$-Liouville Theorems for Hypoelliptic Partial Differential Operators on Lie Groups

open access: yes, 2015
We prove weighted $L^p$-Liouville theorems for a class of second order hypoelliptic partial differential operators $\mathcal{L}$ on Lie groups $\mathbb{G}$ whose underlying manifold is $n$-dimensional space.

On the Gevrey regularity for Sums of Squares of vector fields, study of some models

open access: yes, 2018
The micro-local Gevrey regularity of a class of "sums of squares" with real analytic coefficients is studied in detail.

Calculus, continuity and global wave-front properties for Fourier integral operators on $\mathbf{R}^d$

open access: yes, 2014
We illustrate the composition properties for an extended family of SG Fourier integral operators. We prove continuity results for operators in this class with respect to $L^2$ and weighted modulation spaces, and discuss continuity on $\mathscr{S ...

Hypocoercivity without confinement [PDF]

open access: yes, 2019
In this paper, hypocoercivity methods are applied to linear kinetic equations with mass conservation and without confinement, in order to prove that the solutions have an algebraic decay rate in the long-time range, which the same as the rate of the heat

Global Hypoellipticity and Compactness of Resolvent for Fokker-Planck Operator

open access: yes, 2009
In this paper we study the Fokker-Planck operator with potential V(x), and analyze some kind of conditions imposed on the potential to ensure the validity of global hypoelliptic estimates.

Large-time behavior in non-symmetric Fokker-Planck equations

open access: yes, 2015
We consider three classes of linear non-symmetric Fokker-Planck equations having a unique steady state and establish exponential convergence of solutions towards the steady state with explicit (estimates of) decay rates.
