In mathematics, there is an important branch called set theory in which we study about sets, relations as well as their applications. Particularlyand;order theory (an area of set theory) deals with the order of sets as well as relations, especially binary relation which is defined asand;an ordered pair of elements of a set In order theory, the concept of partially ordered set is a very handy concept. A set which follows partial order relation, is known as a partially ordered set. The relation “$leq$” defined on a setand;is known as partially ordered relation as well as the set is called partially ordered set. Down in this page, we’ll learn about partially ordered set, it is definition as well as related examples. . . . . . . . . .
