โœฆ Synopsis


Let U be a continuous representation of a (connected) locally compact group G in a separated locally convex space E. It is shown that the study of U is equivalent to the study of a family Ui of continuous representations of G in Fr6chet spaces Fi. If U is equicontinuous, the F i are Banach spaces, and the Ui are realized by isometric operators. When U is topologically irreducible, it is Na'tmark equivalent to a Fr6chet (or isometric Banach, in the equicontinuous case) continuous representation. Similar results hold for semi-groups.

## Abstract This paper deals with the study of a mathematical model of photon transport in an interstellar cloud where a localized source is present. The source is represented by a Dirac delta functional. The problem is studied in the setting of locally convex spaces. By means of the theory of semi
