有限秩的相对自由代数

Relatively free algebras of finite rank

Thiago Castilho de Mello, Felipe Yukihide Yasumura

摘要:

设$\mathbb{K}$是特征为零的域,$B=B_0+B_1$是有限维结合超代数.本文研究由$B$的Grassmann包络定义的簇$\mathfrak V$的有限秩相对自由代数的多项式恒等式.我们还考虑了$B$的$k$次Grassmann包络,$G^{(k)}(B)$,用$k$生成的Grassmann代数代替无限维Grassmann代数构造.我们专门研究的代数$UT_2(G)$和$UT_2(G^{(k)})$,这可以被视为格拉斯曼包络和$k$ -次格拉斯曼包络,分别为超代数$UT_2(\mathbb{K}[u])$,其中$u^2=1$。

英文摘要:

Let $\mathbb{K}$ be a field of characteristic zero and $B=B_0+B_1$ a finite dimensional associative superalgebra. In this paper we investigate the polynomial identities of the relatively free algebras of finite rank of the variety $\mathfrak V$ defined by the Grassmann envelope of $B$. We also consider the $k$-th Grassmann Envelope of $B$, $G^{(k)}(B)$, constructed with the $k$-generated Grassmann algebra, instead of the infinite dimensional Grassmann algebra. We specialize our studies for the algebra $UT_2(G)$ and $UT_2(G^{(k)})$, which can be seen as the Grassmann envelope and $k$-th Grassmann envelope, respectively, of the superalgebra $UT_2(\mathbb{K}[u])$, where $u^2=1$.
