我们考虑半单超Tannakian范畴所产生的对象,其对称或交替张量平方是简单的平凡和。利用表示理论,我们提供了一个标准,以确定相应的Tannaka超群,适用于许多情况。作为一个例子,我们讨论的张量范畴产生的卷积幂的代数曲线内的雅可比品种。
We consider semisimple super Tannakian categories generated by an object whose symmetric or alternating tensor square is simple up to trivial summands. Using representation theory, we provide a criterion to identify the corresponding Tannaka super groups that applies in many situations. As an example we discuss the tensor category generated by the convolution powers of an algebraic curve inside its Jacobian variety.
