Some results concerning a transformation semigroup
J. S. V. Symons · Journal of the Australian Mathematical Society · 1975
The full transformation semigroup F(X) is extremely important. As far back as 1952, Malcev (1952) showed that its automorphism group consisted of mappings of the form g-1 · g, g ∈ G(X). The present work is devoted to a generalization of this result.
