Beyond Gevrey regularity [PDF]

open access: yesJournal of Pseudo-Differential Operators and Applications, 2016
We define and study classes of smooth functions which are less regular than Gevrey functions. To that end we introduce two-parameter dependent sequences which do not satisfy Komatsu's condition (M.2)', which implies stability under differential operators

Landau Damping: Paraproducts and Gevrey Regularity [PDF]

open access: yesAnnals of PDE, 2016
We give a new, simpler, proof of nonlinear Landau damping on T^d in Gevrey-1/s regularity (s > 1/3) which matches the regularity requirement predicted by the formal analysis of Mouhot and Villani in the original proof of Landau damping [Acta Mathematica 2011].

Propagation of Gevrey regularity for solutions of Landau equations [PDF]

open access: yesKinetic & Related Models, 2008
By using the energy-type inequality, we obtain, in this paper, the result on propagation of Gevrey regularity for the solution of the spatially homogeneous Landau equation in the cases of Maxwellian molecules and hard ...

Gevrey Regularity for Solution of the Spatially Homogeneous Landau Equation [PDF]

open access: yesActa Mathematica Scientia, 2009
In this paper, we study the Gevrey class regularity for solutions of the spatially homogeneous Landau equations in the hard potential case and the Maxwellian molecules ...

Minimal Gevrey Regularity for Hörmander Operators

open access: yesInternational Mathematics Research Notices, 2023
Abstract We prove a minimal Gevrey regularity theorem for Hörmander’s sum of squares type operators ( 1.1), improving the result of Derridj and Zuily [ 10]. The Gevrey index given here is optimal, in the sense that there are operators of this type that just attain that regularity and not any better.

Extended Gevrey Regularity via Weight Matrices

open access: yesAxioms, 2022
The main aim of this paper is to compare two recent approaches for investigating the interspace between the union of Gevrey spaces Gt(U) and the space of smooth functions C∞(U). The first approach in the style of Komatsu is based on the properties of two parameter sequences Mp=pτpσ, τ>0, σ>1.

On the analyticity and Gevrey class regularity up to the boundary for the Euler Equations [PDF]

open access: yes, 2010
We consider the Euler equations in a three-dimensional Gevrey-class bounded domain. Using Lagrangian coordinates we obtain the Gevrey-class persistence of the solution, up to the boundary, with an explicit estimate on the rate of decay of the Gevrey ...

Contrast between Lagrangian and Eulerian analytic regularity properties of Euler equations [PDF]

open access: yes, 2015
We consider the incompressible Euler equations on ${\mathbb R}^d$, where $d \in \{ 2,3 \}$. We prove that: (a) In Lagrangian coordinates the equations are locally well-posed in spaces with fixed real-analyticity radius (more generally, a fixed Gevrey ...

A Paley–Wiener theorem in extended Gevrey regularity [PDF]

open access: yesJournal of Pseudo-Differential Operators and Applications, 2019
In this paper we introduce appropriate associated function to the sequence $M_p=p^{\t p^{\s}}$, $p\in \N$, $\t>0$, $\s>1$, and derive its sharp asymptotic estimates in terms of the Lambert $W$ function. These estimates are used to prove a Paley-Wiener type theorem for compactly supported functions from extended Gevrey classes.
