Fundamental solutions of homogeneous elliptic differential operators
Brice Camus
We compute fundamental solutions of homogeneous elliptic differential operators, with constant coefficients, on by mean of analytic continuation of distributions. Th…
Spectral estimates for degenerate critical levels
Brice Camus
We establish spectral estimates at a critical energy level for -pseudors . Via a trace formula, we compute the contribution of isolated (non-extremum) critical points under a co…
Spectral fluctuations of Schrödinger operators generated by critical points of the potential
Brice Camus
Starting from the spectrum of Schrödinger operators on , we propose a method to detect critical points of the potential. We argue semi-classically on the basis of a m…
Asymptotic approximation of degenerate fiber integrals
Brice Camus
We study asymptotics of fiber integrals depending on a large parameter. When the critical fiber is singular, full-asymptotic expansions are established in two different cases : loc…
Semi-classical spectral estimates for Schrödinger operators at a critical level. Case of a degenerate maximum of the potential
Brice Camus
We study the semi-classical trace formula at a critical energy level for a Schrödinger operator on . We assume here that the potential has a totally degenerate crit…
