Intersection theories of coherent sheaf stacks and virtual pull-backs via semi-perfect obstruction theories

Sanghyeon Lee

In this paper, we construct proper pushforwards and flat pullbacks in Chow groups of coherent sheaf stacks over a Deligne-Mumford(DM) stack. When there is a relative semi-perfect o…

Splitting of the virtual class for genus one stable quasimaps

Sanghyeon Lee, Mu-Lin Li

We analyse the local structure of moduli space of genus one stable quasimaps. Combining it with the p-fields theory developed in \cite{L}, we prove the splitting formula for the vi…
