Title. Primer of Quasivariety Lattices
Speaker. Joy N. Nishida
Abstract. The lattice of subquasivarieties of a quasivariety can be represented as the lattice of -closed algebraic subsets of an algebraic lattice with a monoid of operators. This representation is used to develop new restrictions on the equational closure operator. A method that enables us to represent some finite lattices as lattices of subquasivarieties is described.
