Course Learning Outcomes

Upon completion of this course, the student will be able to understand basic properties of ordered sets; their diagrams; maps between ordered sets; the duality principle; down-sets and up-sets; maximal and minimal elements; top and bottom; and building new ordered sets,, Learning lattices as ordered sets; complete lattices; chain conditions and completeness; and how to construct complete partially ordered sets. Provides opportunity of learning further rich topics of set theory like the existence of maximal elements and the celebrated Zorn’s Lemma. This course further enables students how to deal with lattices as algebraic structures; to form sublattices; products; homomorphisms. Lattice theory, although a comparatively new branch of Mathematics can no more be treated as still in its infancy. It is fast making inroads into diverse mathematical disciplines and has already made its presence felt in the fields of Toplogy, analysis, algebra, Geometry, Probability and logic.
