A simple graph defines an associated Bernstein superalgebra. Costa and Grishkov showed that graphs with isomorphic algebras are isomorphic using algebraic group techniques. We prove combinatorially that the superalgebra determines the graph for any field of characteristic not 2, and we describe the automorphisms of the superalgebra.

伯恩斯坦图代数

一个简单的图定义了一个相关的伯恩斯坦超代数。Costa和Grishkov表明,使用代数群技术,具有同构代数的图是同构的。我们通过组合证明了超级代数决定了特征不是2的任何场的图,并且我们描述了超级代数的自同构。
