Abstract

LetC e (R n ,G) denote the group of infinitely differentiable maps fromn-dimensional Euclidean space into a simply connected and connected Lie group, which have compact support. This paper introduces a class of factorisable unitary representations ofC e (R n ,G) with the property that the unitary operatorU f corresponding to a functionf inC e (R n ,G) depends not only onf, but also on the derivatives off up to a certain order. In particular these representations can not be extended to the group of all continuous functions fromR n toG with compact support.
