Complex Ginzburg-Landau equations in high dimensions and codimension two area minimizing currents

Fanghua Lin, Tristan Rivière (1999)

Journal of the European Mathematical Society

There is an obvious topological obstruction for a finite energy unimodular harmonic extension of a S 1 -valued function defined on the boundary of a bounded regular domain of R n . When such extensions do not exist, we use the Ginzburg-Landau relaxation procedure. We prove that, up to a subsequence, a sequence of Ginzburg-Landau minimizers, as the coupling parameter tends to infinity, converges to a unimodular harmonic map away from a codimension-2 minimal current minimizing the area within the homology...

Comportement semi-classique du spectre des hamiltoniens quantiques elliptiques

Didier Robert, Bernard Helffer (1981)

Annales de l'institut Fourier

Dans cet article nous généralisons les résultats obtenus par J. Chazarain sur le spectre d’opérateurs de Schrödinger P ( h ) = h 2 2 Δ + V lorsque h 0 . Nous étendons ses résultats aux opérateurs pseudo-différentiels globalement elliptiques d’ordre m > 0 .
