从禁止构形到Monster型轴代数的分类

From forbidden configurations to a classification of some axial algebras of Monster type

Justin McInroy, Sergey Shpectorov

摘要:

伊万诺夫介绍了形状的马约拉纳代数作为记录的$2$ -产生的子代数所产生的代数。作为一个广泛的概括这个概念,并免费从周围的代数,我们介绍的概念,轴和形状的轴。一个形状可以被看作是一个代数版本的一组汞齐。就像一个汞合金,一个形状导致一个唯一的代数完成,它可能是非平凡的,也可能是崩溃的。然后,对于一个自然家庭的形状广义怪物型,我们分类所有完成代数,并发现其中绝大多数崩溃,证实了意见,在以前的文件。

英文摘要:

Ivanov introduced the shape of a Majorana algebra as a record of the $2$-generated subalgebras arising in that algebra. As a broad generalisation of this concept and to free it from the ambient algebra, we introduce the concept of an axet and shapes on an axet. A shape can be viewed as an algebra version of a group amalgam. Just like an amalgam, a shape leads to a unique algebra completion which may be non-trivial or it may collapse. Then for a natural family of shapes of generalised Monster type we classify all completion algebras and discover that a great majority of them collapse, confirming the observations made in an earlier paper.
