对半群树的进一步理解

Towards a Better Understanding of the Semigroup Tree

Maria Bras-Amoros, Stanislav Bulygin

摘要:

在本文中,我们详细说明了半群树的结构和观察到的每个节点的后代的数量的相关性。这些regularites承认两种不同类型的行为,并在这项工作中,我们调查这两种类型发生在特别是著名的类半群。此外,我们研究的问题,什么样的链出现在树和特征的性质(如(在)有限)。最后,我们的一些想法,表明如何研究的半群树可能有助于解决猜想的Fibonacci的行为的半群的数量与给定的属。

英文摘要:

In this paper we elaborate on the structure of the semigroup tree and the regularities on the number of descendants of each node observed earlier. These regularites admit two different types of behavior and in this work we investigate which of the two types takes place in particular for well-known classes of semigroups. Also we study the question of what kind of chains appear in the tree and characterize the properties (like being (in)finite) thereof. We conclude with some thoughts that show how this study of the semigroup tree may help in solving the conjecture of Fibonacci-like behavior of the number of semigroups with given genus.
