Abstract

In this article, we explore the automorphisms of endomorphism semigroups and automorphism groups
of the finite elementary Abelian groups. In particular, we prove that
Aut(End(Zp⊕Zp⊕⋯⊕Zp)) can be canonically embedded into
Aut(Aut(Zp⊕Zp⊕⋯⊕Zp)) using an elementary approach based
on matrix operations. We also show that all automorphisms of End(Zp⊕Zp⊕⋯⊕Zp)
are inner.
