I understand you’re seeking previous GATE exam questions on Lattices in Discrete Mathematics. While I don’t have access to the exact 2025 GATE question paper, I can provide you with a relevant example from past exams to aid your preparation.

Example Question:

Consider the following Hasse diagram representing a partially ordered set (poset):

e
/ \
b c
\ / \
a d

Identify all complements of the element ‘a’ in this lattice.

Solution:

In a lattice, an element ‘x’ is considered a complement of ‘a’ if:

  1. The least upper bound (LUB) of ‘a’ and ‘x’ is the greatest element (often denoted as ‘1’ or ‘I’).
  2. The greatest lower bound (GLB) of ‘a’ and ‘x’ is the least element (often denoted as ‘0’ or ‘O’).

Analyzing the given Hasse diagram:

We need to find elements ‘x’ such that:

Evaluating each element:

Conclusion:

The elements c, d, and e are complements of ‘a’ in the given lattice.

Understanding Lattices and Hasse Diagrams

A lattice is a partially ordered set (poset) in which every pair of elements has both a least upper bound (join) and a greatest lower bound (meet). A Hasse diagram is a graphical representation of a finite poset, where elements are represented as vertices, and edges indicate the order relation without transitive edges.(Scribd)
