用种子计算数值半群

Computation of numerical semigroups by means of seeds

Maria Bras-Amorós, Julio Fernández-González

摘要:

对于数值半群中大于Frobenius数的元素,我们通过扩展生成元的概念,引入了种子的定义。这个新概念允许我们以另一种有效的方式探索半群树,因为每个后代的种子可以很容易地从其父代的种子中获得。本文致力于提出的结果是与这种方法,导致一个新的算法计算和计数的半群给定的亏格。

英文摘要:

For the elements of a numerical semigroup which are larger than the Frobenius number, we introduce the definition of, seed, by broadening the notion of generator. This new concept allows us to explore the semigroup tree in an alternative efficient way, since the seeds of each descendant can be easily obtained from the seeds of its parent. The paper is devoted to presenting the results which are related to this approach, leading to a new algorithm for computing and counting the semigroups of a given genus.
