On Discontinuity of L2-Angle

Piotr Jakóbczak and Tomasz Mazur

(Received 14 March 1988)

Abstract

In this note the L2-angle between two concentric rings and between the ring and the exterior of the disc in the complex plane are calculated. In the second part we prove that the L2-angles between domains A and B and between A ×C and B ×C are equal. We give also some examples of discontinuity of the L2-angle between domains.
