This paper is a survey of recent developments concerning Hilbert spaces \(H\) of analytic functions on bounded symmetric domains \(D\) which are invariant under biholomorphic automorphisms of \(D\), as well as the representation theory of these automorphism groups. The survey is written for a general audience of functional analysts, and some of the works cited are in preprint form.

After reviewing E. Cartan’s classification of \(D\) and the Jordan triple product, the author presents various ways of describing \(H\), including the work of J. Faraut and A. Kornyi [J. Funct. Anal. 88, No. 1, 64-89 (1990; Zbl 0718.32026)] and joint work of the author with S. D. Fisher [Oper. Theory: Adv. Appl. 48, 67-91 (1990; Zbl 0733.46011)], as well as extensions by the author of work by Z. Yan to invariant inner products for Cartan tube domains. He illustrates some of the results by formulating them in case \(D\) is a classical Cartan domain regarded as a space of complex matrices or as the unit ball in complex \(n\)-space, where formulas for the inner products on \(H\) are derived. There are many highly technical results drawing upon various fields of both classical and functional analysis.
