Stationary phase with Cauchy singularity. A critical point of signature $(+,-)$
Abstract
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 phase with a small parameter $h$, $0
