چکیده

In this paper, we are interested in the (as yet) unsolved problem of determining all subsemigroups of $\mathcal{T}(X)$ in which every automorphism is inner. We show that the semigroup of full transformations with restriction on a fixed set is bijective, has an inner automorphism property (i.a.p).
