Let G denote the group of affine transformations on , or one of its subgroups such as the translation group or the Euclidean motion group. In this paper, we study unitarisability of holomorphic representations T of G into the space of square integrable -valued functions with respect to a positive real measure ¦Ì with support in a domain D in . Moreover, we investigate the infinitesimal representation approach of a unitary representation on the Lie algebra of G in order to determine a class of second-order differential operators (called of Ornstein-Uhlenbeck type) invariant with respect to the unitarising measures ¦Ì.
