Abstract
In this paper, we show that two quasi-primal algebras are Morita equivalent if and only if their inverse semigroups of inner automorphisms are isomorphic, and if they have the “same” one-element subalgebras. The proof of this statement uses the representation theory of algebras by sections in sheaves.
