Wilf猜想在仿射半群上的推广

An extension of Wilf's conjecture to affine semigroups

J. I. García-García, D. Marín-Aragón, A. Vigneron-Tenorio

摘要:

设$\CaC\subset \Q^p$为有理锥。当$(\CaC\setminus S)\cap \N^p$只有有限个元素时,仿射半群$S\subset \CaC$是$\CaC$ -半群.本文研究了$\CaC$ -半群的树,给出了生成树的方法,并研究了其具有最小嵌入维数的子半群。本文将数值半群的Wilf猜想推广到$\CaC$ -半群,并给出满足推广猜想的$\CaC$ -半群族.我们还检验了$\CaC$ -半群似乎也满足数值半群上的其它命题。

英文摘要:

Let $\CaC\subset \Q^p$ be a rational cone. An affine semigroup $S\subset \CaC$ is a $\CaC$-semigroup whenever $(\CaC\setminus S)\cap \N^p$ has only a finite number of elements. In this work, we study the tree of $\CaC$-semigroups, give a method to generate it and study their subsemigroups with minimal embedding dimension. We extend Wilf's conjecture for numerical semigroups to $\CaC$-semigroups and give some families of $\CaC$-semigroups fulfilling the extended conjecture. We also check that other conjectures on numerical semigroups seem to be also satisfied by $\CaC$-semigroups.
