About the Course:The objective of this course is to introduce the student to some powerful paradigms in modern combinatorics, namely Möbius inversion on partially ordered sets, combinatorial classes and combinatorial species, and the Lindström-Gessel-Viennot lemma. It will also include an introduction to the theory of symmetric functions.INTENDED AUDIENCE: M.Sc./M.Tech. (Mathematics, Computer Science), PhD coursework (Mathematics, Computer Science), advanced undergraduates, B.Sc., B.E., B.Tech. (Mathematics, Computer Science).PREREQUISITES: Knowledge of set theory, linear algebra, and algebra at the undergraduate level, basic undergraduate discrete mathematics (induction, graphs, trees, basic counting techniques, recurrence relations, etc.).INDUSTRY SUPPORT: Nil
Algebraic Combinatorics
NPTEL and Institute of Mathematical Sciences via Swayam
