The $S^1$ fixed points in Quot-schemes and mirror principle computations

Bong H. Lian, Chien-Hao Liu, Kefeng Liu +1

We describe the $S^1$-action on the Quot-scheme $\Quot({\cal E}^n)$ associated to the trivial bundle ${\cal E}^n=CP^1\times{\smallBbb C}^n$. In particlular, the topology of the $S^…
