Stationary phase with Cauchy singularity. A critical point of signature $(+, -)$

Christian Klein, Johannes SjÃ¶strand, Maher Zerzeri

Asymptotic expressions for an integral appearing in the solution of a d-bar problem are presented. The integral is a solid Cauchy transform of a function with a rapidly oscillating…

Counter-examples to the fractal Weyl law for semiclassical resonances

Jean-Francois Bony, Setsuro Fujiie, Thierry Ramond +1

Under general assumptions, the numbers of semiclassical resonances is known to be bounded from above by a negative power of $h$ which is given by the fractal dimension of the trapp…
