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…
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…
Contributions of non-extremum critical points to the semi-classical trace formula
Brice Camus
We study the semi-classical trace formula at a critical energy level for a -pseudo-differential operator on whose principal symbol has a totally degenerate crit…
