[图书][B] Toric varieties

DA Cox, JB Little, HK Schenck - 2024 - books.google.com
Toric varieties form a beautiful and accessible part of modern algebraic geometry. This book
covers the standard topics in toric geometry; a novel feature is that each of the first nine …

[图书][B] Monomial algebras

RH Villarreal - 2001 - api.taylorfrancis.com
The main purpose of this book is to introduce algebraic, combinatorial, and computational
methods to study monomial algebras and their presentation ideals, including Stanley …

Toric ideals generated by quadratic binomials

H Ohsugi, T Hibi - Journal of Algebra, 1999 - Elsevier
A combinatorial criterion for the toric ideal arising from a finite graph to be generated by
quadratic binomials is studied. Such a criterion guarantees that every Koszul algebra …

Amoebas, nonnegative polynomials and sums of squares supported on circuits

S Iliman, T De Wolff - Research in the Mathematical Sciences, 2016 - Springer
We completely characterize sections of the cones of nonnegative polynomials, convex
polynomials and sums of squares with polynomials supported on circuits, a genuine class of …

Alcoved polytopes, I

T Lam, A Postnikov - Discrete & Computational Geometry, 2007 - Springer
The aim of this paper is to study alcoved polytopes, which are polytopes arising from affine
Coxeter arrangements. This class of convex polytopes includes many classical polytopes …

Koszul algebras

R Fröberg - Advances in commutative ring theory, 2023 - taylorfrancis.com
A graded k-algebra A is called a Ivoszul algebra if the minimal graded free A-resolution of k
has only linear maps. This article is a survey on results obtained about Ivoszul algebras …

Multigraded castelnuovo-mumford regularity

D Maclagan, GG Smith - 2004 - degruyter.com
We develop a multigraded variant of Castelnuovo-Mumford regularity. Motivated by toric
geometry, we work with modules over a polynomial ring graded by a finitely generated …

h-vectors of Gorenstein polytopes

W Bruns, T Römer - Journal of Combinatorial Theory, Series A, 2007 - Elsevier
We show that the Ehrhart h-vector of an integer Gorenstein polytope with a regular
unimodular triangulation satisfies McMullen's g-theorem; in particular, it is unimodal. This …
