Multi-algebras as tolerance quotients of algebras

Rings and Algebras 2022-08-09 v1

Abstract

If AA is an algebra and \bgt is a tolerance on AA, then A/\bgtA/\bgt is a multi-algebra in a natural way. We give an example to show that not every multi-algebra arises in this manner. We slightly generalize the construction of A/\bgtA/\bgt and prove that every multi-algebra arises from this modified construction.
