WebI have a belief: math, science, machine learning, etc., are all easy to understand! Why do they look so hard, then? Because very often, beautiful concepts are hidden behind layers upon layers of abstraction, making them unnecessarily complex. My goal is to pull the curtain and demystify these topics by explaining … WebMay 21, 2024 · A commutative monoid is called an affine monoid if it is isomorphic to a finitely generated submonoid of ℤ n \mathbb{Z}^n, and there is an extensive theory of these, connected to toric varieties (see BrunsGubeladze).
WebJan 15, 2024 · Affine monoid algebra 1. Introduction When considering monoid algebras , an immediate question is whether certain properties of the domain D and the monoid S carry over to the monoid algebra and conversely. A lot of such properties are studied in the textbook by Gilmer [18], among them the property of being a Krull domain. WebJames Milne -- Home Page
WebJul 6, 2016 · This affine monoid has a (unique) minimal generating system called the Hilbert basis \({\text {Hilb}}(M)\), see Fig. 1 for an example. The computation of the Hilbert basis is the first main task of Normaliz. One application is the computation of the normalization of an affine monoid M; this explains the name Normaliz.

I ask because I'm not completely certain: I don't know what dangers lie for intuition outside free abelian groups. If it is, then it seems like the same proof as for polynomial rings would hold. $\endgroup$ – rschwieb bluey s3 e32WebJul 31, 2007 · Michigan Mathematical Journal. In this note we consider monoidal complexes and their associated algebras, called toric face rings. These rings generalize Stanley-Reisner rings and affine monoid algebras.
