Basic properties of lattices:

lattices as ordered sets, algebraic concept, homomorphisms, congruences and ideals, join-irreducible elements

Distributive lattices:

characterization, free distributive lattices, congruences of distributive lattices, topological representation

Congruences and ideals:

weak projectivity and perspectivity, distributive, standard and neutral elements and ideals, congruences of a cartesian product, modular and weakly modular lattices, distributivity of the congruence lattice of a lattice

Modular and semimodular lattices:

characterization, Kurosh-Ore theorem, congruences in modular lattices, von Neumann theorem, Birghoff theorem, semimodular lattices, Jordan-Hölder theorem, geometric lattices, partition lattices, complemented modular lattices and projective geometries
