Abstract

The authors consider the problem of recovering a holomorphic function defined in a domain Ω of the complex plane from its values at an infinite sequence of points (z n ) in Ω converging to a point in Ω. The problem, which is ill-posed, is regularized by various methods. Necessary and sufficient conditions for existence are given.
