Partial Orders (POSETs)

Partial Orders (POSETs). Partial order or POSET. Definitions : A relation R on a set A is called a partial order if it is Reflexive Antisymmetric Transitive set A together with a partial ordering R is called a partially ordered set (poset, for short) and is denote by [ A;R ]
