Title:

A remark on some punctual Quot schemes on smooth projective curves

Abstract：

For a locally free sheaf $E$ on a smooth projective curve, we can define the punctual Quot scheme which parametrizes torsion quotients of $E$ of length $n$ supported at a fixed point. It is known that the punctual Quot scheme is a normal projective variety with canonical Gorenstein singularities. In this talk, I explain that the punctual Quot scheme is a $\mathbb{Q}$-factorial Fano variety of Picard number one.
