Applications of Algebraic Combinatorics to Algebraic Geometry [PDF]
Indagationes Mathematicae, 2021 We formulate a number of new results in Algebraic Geometry and outline their derivation from Theorem 2.12 which belongs to Algebraic Combinatorics.

On the Combinatorics of Gentle Algebras [PDF]
Canadian Journal of Mathematics, 2019 AbstractFor $A$ a gentle algebra, and $X$ and $Y$ string modules, we construct a combinatorial basis for $\operatorname{Hom}(X,\unicode[STIX]{x1D70F}Y)$. We use this to describe support $\unicode[STIX]{x1D70F}$-tilting modules for $A$. We give a combinatorial realization of maps in both directions realizing the bijection between support $\unicode[STIX]{

Algebraic combinatorics in bounded induction [PDF]
Annals of Pure and Applied Logic, 2021 In this paper, new methods for analyzing models of weak subsystems of Peano Arithmetic are proposed. The focus will be on the study of algebro-combinatoric properties of certain definable cuts. Their relationship with segments that satisfy more induction, with those limited by the standard powers/roots of an element, and also with definable sets in ...

Geometric and algebraic combinatorics
European Journal of Combinatorics, 2007 The present issue of the European Journal of Combinatorics contains papers on finite incidence geometries, combinatorial designs, and algebraic graph theory, captured by the name Geometric and Algebraic Combinatorics. This name, abbreviated to GAC, is also carried by a series of conferences held in Oisterwijk, The Netherlands.

Combinatorics of the Free Baxter Algebra [PDF]
The Electronic Journal of Combinatorics, 2006 We study the free (associative, non-commutative) Baxter algebra on one generator. The first explicit description of this object is due to Ebrahimi-Fard and Guo. We provide an alternative description in terms of a certain class of trees, which form a linear basis for this algebra.

A survey of semisimple algebras in algebraic combinatorics [PDF]
Indian Journal of Pure and Applied Mathematics, 2021 This is a survey of semisimple algebras of current interest in algebraic combinatorics, with a focus on questions which we feel will be new and interesting to experts in group algebras, integral representation theory, and computational algebra. The algebras arise primarily in two families: coherent algebras and subconstituent (aka.

Combinatorics of free vertex algebras [PDF]
Journal of Algebra, 2002 This paper illustrates the combinatorial approach to vertex algebra - study of vertex algebras presented by generators and relations. A necessary ingredient of this method is the notion of free vertex algebra. Borcherds \cite{bor} was the first to note that free vertex algebras do not exist in general. The reason for this is that vertex algebras do not
