WebSome important definitions related to lattice are given below: 1. Lattice: A partial order set (POS) (A, ≤) is called a lattice if, x, y ε A, there exist sup(x, y) and inf (x, y) [27]. For supermum we use the symbol and for infimum we use the symbol .In the lattice theory, these operations are called binary operations. 2.
