Testing analyticity on circles

Research output: Contribution to journalArticlepeer-review

Abstract

Consider a continuous one parameter family of circles in a complex plane that contains two circles lying in the exterior of one another. We prove that if a continuous function on the union of the circles extends holomorphically into each circle, then the function is holomorphic in the interior of the union of the circles.
