Algebraic combinatorics
My papers in arXiv. QSP Book Chapters. I have research interests in the following subjects: Quantum groups, i-quantum groups, and canonical bases. Hecke algebras: finite, affine, and spin. (Spin) symmetric groups and algebraic q-combinatorics. Infinite-dimensional Lie algebras and vertex algebras.3. I'm learning combinatorics and need a little help differentiating between a combinatorial proof and an algebraic proof. Here is an example I came across: Prove the following two formulas by combinatorial means and algebraic manipulation: (i) For all k, n ∈ N with k ≤ n. (n2) +(n+12) =n2. (ii) For all k, n ∈N with k ≤ n.

Algebra. Algebra provides the mathematical tools to find unknown quantities from related known ones, the famous quadratic equation being a familiar example. The subject interacts with all of mathematics as well as many applied fields. For instance, symmetries of pyramids or cubes, or indeed any object, can be viewed through the lens of algebra.Combinatorics and Discrete Geometry. Combinatorics is the study of finite structures, many of which arise in other branches of mathematics or from problems arising in science or engineering. The study of combinatorics involves general questions of enumeration and structure, matroid theory and aspects of graph theory, partially ordered sets, set ...Cambridge Notes. Cambridge Notes.

Much instruction in combinatorics is problem-based, and particular counting problems are leveraged to develop and apply important combinatorial methods and practices. Algebra teaching, in contrast, can often follow a much stricter (less problem-based) procedural approach to learning algebraic methods. 4 However, this need not be the case, and ...2009–2012, Principal Investigator, NSF grant DMS 0901298, $379,101, Invariant Theory and Algebraic Combinatorics.
