Hasse diagram

HASSE DIAGRAM

Hasse Diagram: Hasse diagram generally used to represent partial order relations in equivalent but in simpler forms by removing non critical parts of the relation.

For example:




Below diagram represent a partial order relation.

This can relation can be modify as-
  1. Remove all loops.
  2. Remove all arrows that can be inferred from transitivity.

Than above diagram represented as-



Above diagram is known as Hasse diagram for a partial order relation.
