Conjugacy classes of automorphisms of the unit ball in a complex Hilbert space
Rachna Aggarwal, Krishnendu Gongopadhyay, Mukund Madhav Mishra
In this article, we consider the ball model of an infinite dimensional complex hyperbolic space, i.e. the open unit ball of a complex Hilbert space centered at the origin equipped…

Fixed points and normal automorphisms of the unit ball of bounded operators on
Rachna Aggarwal, Krishnendu Gongopadhyay, Mukund Madhav Mishra
We examine the group of isometries of the open unit ball of a complex Banach space of certain bounded linear operators equipped with the Carathéodory metric. Therein we obtain a ch…
