Sharp estimates for discrete second order {R}iesz transforms

Komla Domelevo, Stefanie Petermichl

We show that multipliers of second order Riesz transforms on products of discrete abelian groups enjoy the estimate , where and $p…

Diffusions with polynomial eigenvectors via finite subgroups of O(3)

Dominique Bakry, Xavier Bressaud

We provide new examples of diffusion operators in dimension 2 and 3 which have orthogonal polynomials as eigenvectors. Their construction rely on the finite subgroups of O(3) and t…

Non-convex Regularizations for Feature Selection in Ranking With Sparse SVM

Léa Laporte, Rémi Flamary, Stephane Canu +2

Feature selection in learning to rank has recently emerged as a crucial issue. Whereas several preprocessing approaches have been proposed, only a few works have been focused on in…

On a three-dimensional free boundary problem modeling electrostatic mems

Philippe Laurencot, Christoph Walker

We consider the dynamics of an electrostatically actuated thin elastic plate being clamped at its boundary above a rigid plate. The model includes the harmonic electrostatic potent…

A class of Hamilton-Jacobi equations with constraint: uniqueness and constructive approach

Sepideh Mirrahimi, Jean-Michel Roquejoffre

We discuss a class of time-dependent Hamilton-Jacobi equations, where an unknown function of time is intended to keep the maximum of the solution to the constant value 0. Our main…

Systèmes de points dans les dg-catégories saturées

B. Toën, M. Vaquié

In this work we consider the question of realizing triangulated dg-categories by derived categories of algebraic varieties. For this, we introduce the notion of "system of points"…
