Automorphisms of the semigroup of invertible matrices with nonnegative elements over commutative partially ordered rings

E. I. Bunina, P. P. Semenov

Suppose that R is an ordered ring, G_n(R) is a subsemigroup of $G{L}_n(R)$, consisting of all matrices with nonnegative elements. A.V. Mikhalev and M.A. Shatalova described all autom…
