Given a foundation locally compact Hausdorff topological semigroup S , we consider on M_a ( S )* the τ_c -topology, i.e. the weak topology under all right multipliers induced by measures in M_a ( S ). For such an arbitrary S the τ_c -topology is not weaker than the weak*-topology and not stronger than the norm topology on M_a ( S )*. However, a further investigation shows that for compact S the norm topology and τ_c -topology coincide on every norm bounded subset of M_a ( S ). Among the other results we mention that except for discrete S the τ_c -topology is always different from the norm-topology. Finally, we give some results about τ_c -almost periodic functionals.
