Equivalence Classes and Relations

This lecture covers the concept of equivalence classes, their graphical representation, and their application in decomposing sets into classes of equivalence. It also discusses relations, including reflexive, symmetric, and transitive properties, and their visualization. The lecture further explores the construction of quotient sets, defining equivalence relations, and the classes of equivalence. It concludes with functions, their properties, and the distinction between surjective and injective functions.
