Inequalities and Asymptotic Formulas in Algebraic Combinatorics [PDF]

open access: yes, 2022
This thesis concerns certain inequalities and asymptotic formulas in algebraic combinatorics. It consists of two separate parts. The first part studies inequalities concerning triangular-grid billiards and plabic graphs of Lam–Postnikov essential ...

Valued Graphs and the Representation Theory of Lie Algebras

open access: yesAxioms, 2012
Quivers (directed graphs), species (a generalization of quivers) and their representations play a key role in many areas of mathematics including combinatorics, geometry, and algebra.

Representation zeta functions of compact p-adic analytic groups and arithmetic groups [PDF]

open access: yes, 2013
We introduce new methods from p-adic integration into the study of representation zeta functions associated to compact p-adic analytic groups and arithmetic groups.

Some representations for inverse rising factorial moments

open access: yesMathematical and Computer Modelling of Dynamical Systems
Inverse rising factorial moments [Formula: see text] are fundamental quantities for positive integer-valued random variables, with broad applications in probability and combinatorics.

Topology of matching complexes of complete graphs via discrete Morse theory [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
Bouc (1992) first studied the topological properties of $M_n$, the matching complex of the complete graph of order $n$, in connection with Brown complexes and Quillen complexes. Bj\"{o}rner et al. (1994) showed that $M_n$ is homotopically $(\nu_n-1)$

Chain algebras of finite distributive lattices [PDF]

open access: yes
We introduce a family of toric algebras defined by maximal chains of a finite distributive lattice. Applying results on stable set polytopes we conclude that every such algebra is normal and Cohen-Macaulay, and give an interpretation of its Krull ...

Polynomials in algebraic combinatorics [PDF]

open access: yes, 2018
A long-standing theme in algebraic combinatorics is to study bases of the rings of symmetric functions, quasisymmetric functions, and polynomials. Classically, these bases are homogeneous functions, however, the introduction of K-theoretic combinatorics

A centralizer analogue to the Farahat-Higman algebra [PDF]

open access: yes
We define a family of algebras FHm which generalise the Farahat-Higman algebra introduced in [4] by replacing the role of the center of the group algebra of the symmetric groups with centraliser algebras of symmetric groups.

Splines on Cayley graphs of the symmetric group

open access: yesForum of Mathematics, Sigma
A spline is an assignment of polynomials to the vertices of a graph whose edges are labeled by ideals, where the difference of two polynomials labeling adjacent vertices must belong to the corresponding ideal. The set of splines forms a ring. We consider
