In this paper we develop a theory of localization for bounded commutative BCK-algebras. We try to extend some results from the case of commutative Hilbert algebras (see [1]) to the case of commutative BCK-alge- bras.

We give conditions when a weak*-closed left translation invariant subspace in Ma,(S)* of a compact cancellative foundation semigroup S is the range of a weak*-weak* continuous projection on M~,(S)* commuting with translations. Let G be a locally compact group and A be a Banach G-module. Our second purpose in this paper is to study some projections on A* and /3(A*) which commutes with translations and convolution.展开更多
