Best constants in Sobolev and Gagliardo-Nirenberg inequalities on graded groups and ground states for higher order nonlinear subelliptic equations [PDF]

, 2020
In this paper the dependence of the best constants in Sobolev and Gagliardo-Nirenberg inequalities on the precise form of the Sobolev space norm is investigated.

Subelliptic equations : control, singularities and spectral theory

, 2021
Dans cette thèse à la frontière entre analyse et géométrie, nous étudions des équations aux dérivées partielles (EDPs) sous-elliptiques en utilisant des outils récents de géométrie sous-Riemannienne et d'analyse microlocale. Nous étudions tout d'abord la

Regularity at the boundary for solutions of nonlinear subelliptic equations [PDF]

Indiana University Mathematics Journal, 1995
We establish an estimate, in terms of subelliptic \(p\)-capacity, for the modulus of continuity at the boundary of the solution to the Dirichlet problem associated to a class of subelliptic equations. We infer from it the sufficiency part of a Wiener type criterion for the regularity of boundary points.

Exact observability properties of subelliptic wave and Schrödinger equations

, 2021
In this survey paper, we report on recent works concerning exact observability (and, by duality, exact controllability) properties of subelliptic wave and Schrödinger-type equations.

The subelliptic Infinity-Laplace system on Carnot-Caratheodory Spaces [PDF]

, 2013
Given a Carnot-Carathéodory space Ω ⊆ ℝn with associated frame of vector fields X = {X1,⋯, Xm}, we derive the subelliptic ∞-Laplace system for mappings u: Ω → ℝN, which reads δX∞u:=(Xu ⊗ Xu +Xu2[Xu]⊥ ⊗ I): X Xu = 0 in the limit of the subelliptic p ...

The universal family of punctured Riemann surfaces is Stein

Bulletin of the London Mathematical Society, Volume 58, Issue 5, May 2026.
Abstract We show that the universal Teichmüller family V(g,n)$V(g,n)$ of compact Riemann surfaces of genus g⩾0$g\geqslant 0$ with n>0$n>0$ punctures is a Stein manifold. We describe its basic function‐theoretic properties and pose some challenging questions. We show, in particular, that the space of fibrewise algebraic functions on the universal family
