In this paper, we characterize the Johnson pseudo-contractibility of 1(S), where S is a uniformly locally finite inverse semigroup. We show that for a Brandt semigroup S = M0(G, I ) over a non-empty set I, 1(S) is Johnson pseudo-contractible if and only if G is amenable and I is finite. We give some examples to show the difference between Johnson pseudo-contractibility, pseudo-amenability and pseudo contractibility among the semigroup algebras.
