Matroids and convex geometry in combinatorics and algebra [PDF]

, 2019
This thesis is a compendium of three studies on which matroids and convex geometry play a central role and show their connections to Catalan combinatorics, tiling theory, and factorization theory.

$\mathcal {T}$-semiring pairs

, 2022
summary:We develop a general axiomatic theory of algebraic pairs, which simultaneously generalizes several algebraic structures, in order to bypass negation as much as feasible.

Combinatorics of toric arrangements

, 2019
In this paper we build an Orlik–Solomon model for the canonical gradation of the cohomology algebra with integer coecients of the complement of a toric arrangement.

Grassmannians over rings and subpolygons

, 2022
We investigate special points on the Grassmannian which correspond to friezes with coefficients in the case of rank two. Using representations of arithmetic matroids we obtain a theorem on subpolygons of specializations of the coordinate ring.

The h-vectors of matroids and the arithmetic degree of squarefree strongly stable ideals

, 2008
Making use of algebraic and combinatorial techniques, we study two topics: the arithmetic degree of squarefree strongly stable ideals and the h-vectors of matroid complexes.

A lattice framework for generalizing shellable complexes and matroids

28 pages, 1 figureWe introduce the notion of power lattices that unifies and extends the equicardinal geometric lattices, Cartesian products of subspace lattices, and multiset subset lattices, among several others.
