分次单代数的恒等式

Identities of graded simple algebras

Dušan D. Repovš, Mikhail V. Zaicev

摘要:

本文研究了特征为零的域上有限维代数的恒等式,其分次为任意群胚$Γ$。首先证明了它的分次长度有多项式有界增长。对分次单代数$A$,证明了分次PI指数的存在性,条件是$Γ$是交换半群.如果$A$是非分次意义下的单的,则证明了分次PI指数的存在性,而对$Γ$没有任何限制.

英文摘要:

We study identities of finite dimensional algebras over a field of characteristic zero, graded by an arbitrary groupoid $Γ$. First we prove that its graded colength has a polynomially bounded growth. For any graded simple algebra $A$ we prove the existence of the graded PI-exponent, provided that $Γ$ is a commutative semigroup. If $A$ is simple in a non-graded sense the existence of the graded PI-exponent is proved without any restrictions on $Γ$.
