    It is formulated (using the language of (dht-)category to describe partial algebras) Theorem 10.2 (main result of this paper): There is an isomorphism between the complete lattice Con Ṯ of all congruences on a partial theory Ṯ and the complete lattice of all fully invariant strictly algebraic closure operators (on the systems of filters of subidentities of Ṯ).
