Abstract

Conformal mapping is a useful tool in science and engineering. On the other hand exact mapping functions are unknown except for some special regions.
In this paper we present a new boundary integral equation with classical Neumann kernel associated to f f , where f is a conformal mapping of
bounded multiply connected regions onto a disk with circular slit domain. This boundary integral equation is constructed from a boundary relationship
satisfied by a function analytic on a multiply connected region. With f f known, one can then treat it as a differential equation for computing f .
