Muhammad Arfan AliFA12-PMATH-002Dr. Sarfarz AhmadLHR TP 59452026-04-292019https://repository.cuilahore.edu.pk/123456789/3753This work investigates fundamental combinatorial properties of graphs and partially ordered sets (posets), focusing on structural relationships, ordering principles, and enumeration techniques. Concepts from Graph Theory and Order Theory are used to analyze connectivity, comparability, chains, antichains, and lattice structures. The study highlights how these discrete frameworks can be applied to solve problems in optimization, data organization, and theoretical computer science. Emphasis is placed on key invariants and combinatorial methods that reveal deeper insights into the organization and behavior of discrete systems.enDepartment of MathematicsFA12MathematicsGraphsPosetsCombinatoricsGraph TheoryOrder TheoryDr. Sarfarz AhmadThesis
