Optimal Uniform Elliptic Estimates for the Ginzburg-Landau System

S. Fournais, B. Helffer

We reconsider the elliptic estimates for magnetic operators in two and three dimensions used in connection with Ginzburg-Landau theory. Furthermore we discuss the so-called blow-up…

Subelliptic estimates for some systems of complex vector fields : quasihomogeneous case

Makhlouf Derridj, Bernard Helffer

For about twenty five years it was a kind of folk theorem that complex vector-fields defined on Ω×Rt​ (with Ω open set in Rn) by $$ L_j = \frac{\partia…
