关于$M_nE^2$和$M_nE^3$的最小度标准恒等式

The Minimal Degree Standard Identity on $M_nE^2$ and $M_nE^3$

Barbara Anna Balázs, Szabolcs Mészáros

摘要:

本文证明了Grassmann代数的Amitsur-Levitzki型定理,指出$m$生成的Grassmann代数上的$n \times n$矩阵环的多项式恒等式的标准恒等式的最小次数至少对所有$n,m\geq 2$为$2\left\lfloor\frac{m}{2}\right\rfloor+4n-4$,并且这个界对$m=2,3$和任何$n\geq 2$都是尖锐的.参数是纯组合的,基于计算对应于有向图中欧拉轨迹的符号和。

英文摘要:

We prove an Amitsur--Levitzki-type theorem for Grassmann algebras, stating that the minimal degree of a standard identity that is a polynomial identity of the ring of $n \times n$ matrices over the $m$-generated Grassmann algebra is at least $2\left\lfloor\frac{m}{2}\right\rfloor+4n-4$ for all $n,m\geq 2$ and this bound is sharp for $m=2,3$ and any $n\geq 2$. The arguments are purely combinatorial, based on computing sums of signs corresponding to Eulerian trails in directed graphs.
