Professor Themistocles M. Rassias' special predilection and contribution to the study of Möbius transformations is well known. Möbius transformations of the open unit disc of the complex plane and, more generally, of the open unit ball of any real inner product space, give rise to Möbius addition in the ball. The latter, in turn, gives rise to Möbius(More)
