辛反射代数$H_{1,ν}(I_2(2m+1))$中由迹或超迹生成的理想

Ideals generated by traces or by supertraces in the symplectic reflection algebra $H_{1,ν}(I_2(2m+1))$

摘要:

对于每一个复数$ν$,一个基于由根系$I_2(2m+1)$生成的群的结合辛反射代数$\mathcal H:= H_{1,ν}(I_2(2m+1))$具有一个$m$维迹空间和一个$(m+1)$维超迹空间.如果对应的双线性(超)对称形式$B_{sp}(x,y)=sp(xy)$是退化的,则称(超)迹$sp$是退化的。我们发现所有的值的参数$ν$的轨迹的空间包含一个退化的非零轨迹或空间的超轨迹包含一个退化的非零超轨迹,因此,代数$\mathcal H$有一个双边理想的零向量。对代数$H_{1,ν_1, ν_2}(I_2(2m))$也给出了类似的结果。

英文摘要:

For each complex number $ν$, an associative symplectic reflection algebra $\mathcal H:= H_{1,ν}(I_2(2m+1))$, based on the group generated by root system $I_2(2m+1)$, has an $m$-dimensional space of traces and an $(m+1)$-dimensional space of supertraces. A (super)trace $sp$ is said to be degenerate if the corresponding bilinear (super)symmetric form $B_{sp}(x,y)=sp(xy)$ is degenerate. We find all values of the parameter $ν$ for which either the space of traces contains a degenerate nonzero trace or the space of supertraces contains a degenerate nonzero supertrace and, as a consequence, the algebra $\mathcal H$ has a two-sided ideal of null-vectors. The analogous results for the algebra $H_{1,ν_1, ν_2}(I_2(2m))$ are also presented.
