Min-max -harmonic maps of degree 1 with free-boundary into in almost round balls

Dorian Martino, Katarzyna Mazowiecka, Rémy Rodiac

Let and let be a bounded domain which is diffeomorphic to a ball. We investigate here the problem of finding critical points of t…

A Lavrentiev phenomenon in the neo-Hookean model

Marco Barchiesi, Duvan Henao, Carlos Mora-Corral +1

We exhibit a Lavrentiev gap phenomenon for the neo-Hookean energy in three-dimensional nonlinear elasticity. More precisely, we construct boundary data for which the infimum of the…

Critical points of the two-dimensional Ambrosio-Tortorelli functional with convergence of the phase-field energy

Jean-François Babadjian, Martin Rakovsky, Rémy Rodiac

We consider a family of critical points of the Ambrosio-Tortorelli functional. Assuming a uniform energy bound, the sequence $\…

Ginzburg-Landau minimizers with high topological degrees in an annulus

Amandine Aftalion, Rémy Rodiac

Motivated by recent experiments on fermionic rings, we study the asymptotic behaviour of minimizers of the Ginzburg-Landau (GL) energy in an annulus with a Dirichlet data which dep…

A weak energy identity for -harmonic maps with a free boundary in a sphere

Dorian Martino, Katarzyna Mazowiecka, Rémy Rodiac

In this article, we show that sequences of -harmonic maps with a free boundary in , where is a parameter tending to zero, converge to a bubble tree. F…

Mean-field limit of 2D stationary particle systems with signed Coulombian interactions

Jan Peszek, Rémy Rodiac

We study the mean-field limits of critical points of interaction energies with Coulombian singularity. An important feature of our setting is that we allow interaction between part…
