Original abstract

In the paper, we introduce the concept of a preorder on a category and study its relation to categorical closure operators. In particular, employing a Galois connection, we show that there is a one-to-one correspondence between the idempotent closure operators and certain preorders on a category.

Keywords in English

Subobject lattice, Galois connection, categorical closure operator, preorder on a category.
