lattice theory (countable and uncountable, plural lattice theories)

(mathematics, uncountable) The branch of mathematics concerned with lattices (partially ordered sets).

  Apart from an introduction of effective techniques, a most significant contribution of our work has been the elevation of lattice theory in computational intelligence – soft computing.

  Formal Concept Analysis is a mathematical theory of concept hierarchies which is based on Lattice Theory.
(physics, countable and uncountable) A lattice model, a mathematical model based on a lattice (discrete subgroup of Rⁿ); the study of such models.
(particle physics, countable and uncountable) (A) lattice gauge theory.

  It is natural to think that the absence of phase transitions in the SU(2) theory can be generalized to lattice theories with any continuous non-Abelian gauge group.
