Question

Draw the Hasse diagram for the greater than or equal to relation on \(\{ 0,1,2,3,4,5\} \).

Short answer

The Hasse diagram for \(\{ (0,1,2,3,4,5), \ge \} \)

Step-by-step solution

Given data

Given data is \(\{ 0,1,2,3,4,5\} \).

Concept used Hasse diagram

Hasse diagrams are obtained from a directed graph of a partial ordering by,

1) Removing all loops due to reflexivity from the graph of a partial ordering.

2) Removing all edges occurring due to transitivity of the partial ordering.

3) Arranging all edges to point upwards and deleting (directional) arrows

Thus to get all ordered pairs ordered pairs in the partial ordering for a given Hasse diagram, we look for pairs\((x,y)\)such that path from\(x\)to\(y\)is going upwards . In addition, we also need to add pairs of the form\((x,x)\)to account for reflexive pairs (loops).

Draw the Hasse diagram

Consider greater than or equal to relation on \(\{ 0,1,2,3,4,5\} \) which is represented as \(\{ (0,1,2,3,4,5), \ge \} \). The Hasse diagram for \(\{ (0,1,2,3,4,5), \ge \} \)

Hence, Hasse diagram for greater than or equal to relation on \(\{ 0,1,2,3,4,5\} \) is drawn.
