The space LUC(G) of bounded uniformly continuous functions on G has a prominant role in abstrac harmonic analysis. It is a Banach space with the sup norm. Its dual LUC(G)* is a Banach algebra in which the multiplication is the convolution opration *, defined as follows. When is an expression with several parameters, as a function of x. Define Here is the canonical left action of LUC(G)* on LUC(G).
