The four main topics covered will be: enumeration, probabilistic methods, extremal graph theory, and algebraic methods in combinatorics.Algebraic Combinatorics is an area of mathematics that employs methods of abstract algebra, notably group theory and representation theory, in various combinatorial contexts and, conversely, applies combinatorial techniques to problems in algebra and representation theory. Many of its problems arise from the need ofIn algebraic combinatorics, association schemes provide a unified approach to many topics, for example combinatorial designs and the theory of error-correcting codes. [4] [5] In algebra, association schemes generalize groups , and the theory of association schemes generalizes the character theory of linear representations of groups .

The topics include the matrix-tree theorem and other applications of linear algebra, applications of commutative and exterior algebra to counting faces of simplicial complexes, and applications of algebra to tilings.Combinatorics is the study of nite structures that combine via a nite set of rules. Alge-braic combinatorics uses algebraic methods to help you solve counting problems. Often algebraic problems are aided by combinatorial tools; combinatorics thus becomes quite interdisciplinary.The theory of symmetric functions plays a significant role in algebra combinatorics. Al-though the definition of symmetric functions is rooted in combinatorics, symmetric func-tions appear in, beyond combinatorics, many other fields, e.g., representation theory, alge-braic geometry, probability theory, and more.
