Stationary -harmonic maps approaching planar singular harmonic maps to the circle
Marco Badran, Jean Van Schaftingen
Given a bounded planar domain , we show that any singular harmonic map into the circle corresponding to a topologically nondegenerate critical…
The extension of traces for Sobolev mappings between manifolds
Jean Van Schaftingen
The compact Riemannian manifolds and for which the trace operator from the first-order Sobolev space of mappings $\smash{\dot{W}}^{1, p} (\mathcal{M}, \…
Limiting behavior of minimizing -harmonic maps in 3d as goes to with finite fundamental group
Bohdan Bulanyi, Jean Van Schaftingen, Benoît Van Vaerenbergh
We study the limiting behavior of minimizing -harmonic maps from a bounded Lipschitz domain to a compact connected Riemannian manifold without boundary…
Quantitative characterization of traces of Sobolev maps
Katarzyna Mazowiecka, Jean Van Schaftingen
We give a quantitative characterization of traces on the boundary of Sobolev maps in , where and are compact Riem…
Ginzburg-Landau relaxation for harmonic maps on planar domains into a general compact vacuum manifold
Antonin Monteil, Rémy Rodiac, Jean Van Schaftingen
We study the asymptotic behaviour, as a small parameter tends to zero, of minimisers of a Ginzburg-Landau type energy with a nonlinear penalisation potential vanishin…
Renormalised energies and renormalisable singular harmonic maps into a compact manifold on planar domains
Antonin Monteil, Rémy Rodiac, Jean Van Schaftingen
We define renormalised energies for maps that describe the first-order asymptotics of harmonic maps outside of singularities arising due to obstructions generated by the boundary d…
Vortex motion for the lake equations

Semiclassical stationary states for nonlinear Schrödinger equations under a strong external magnetic field
Jonathan Di Cosmo, Jean Van Schaftingen
We construct solutions to the nonlinear magnetic Schrödinger equation $$ \left\{ \begin{aligned} - \varepsilon^2 Δ_{A/\varepsilon^2} u + V u &= \lvert u\rvert^{p-2} u & &\text{in}\…
Desingularization of vortex rings and shallow water vortices by semilinear elliptic problem
Sébastien de Valeriola, Jean Van Schaftingen
Steady vortices for the three-dimensional Euler equation for inviscid incompressible flows and for the shallow water equation are constructed and showed to tend asymptotically to s…
Limiting fractional and Lorentz spaces estimates of differential forms
Jean Van Schaftingen
We obtain estimates in Besov, Lizorkin-Triebel and Lorentz spaces of differential forms on R^n in terms of their L^1 norm.
