Abstract
In this article, as the integral path is an open arc, we discuss the stability of a Cauchy-type integral with kernel density of class H* when a perturbation of the integral path occurs. And we discuss the stability of the Cauchy kernel singular integral with a kernel density of class H* when a perturbation of the integral path occurs.
Cauchy-type integral:
