Non-modular and non-distributive primitive ordered subsets of lattices
Jiří Rachůnek · Czech digital mathematics library · 1993
Lattices not containing an isomorphic copy of a member from a given set of finite ordered sets as a primitive subset form a variety of lattices.In the paper some collections of primitive ordered sets characterising the variety of distributive lattices and two small nondistributive varieties of lattices are shown.
