Abstract

Let G be a locally compact group and let μ be a regular, compactly supported, complex-valued Borel measure on G. In the present paper, we determine the continuous solutions f,g : G → C of the functional equation fG f(xyt) + f(xy-1t)dμ(t) = 2g(x)f(y), x,y G, in terms of characters, additive maps and matrix elements of irreducible, two-dimensional representations of G. Many consequences of this result are presented. © 2016 by De Gruyter 2016.
