Description
Résumé:Using the non&#45;abelian Fourier transform, we find the central continuous solutions of the functional equation <img src="http:/fbpe/img/proy/v34n3/art07_for1.jpg" width="300" height="47"> where G is an arbitrary compact group, <img src="http:/fbpe/img/proy/v34n3/art07_for2.jpg" width="200" height="43"> and &#963; is a continuous automorphism of G, such that &#963;n = I. We express the solutions in terms of the unitary (group) characters of G.
