Virtual normalization and virtual fundamental classes
Year: 2011
Type: preprint
Abstract: In this paper, we compare the virtual fundamental classes of the stacks of $(g,β,μ)$-stable ramified maps $\bar{\mathfrak U}_{g,μ}(X,β)$ and of $(g,β,μ)$-log stable ramified maps $\bar{\mathfrak U}^{\mathrm{log}}_{g,μ}(X,β)$. For that we will see how they are identified via virtual normalization and then apply Costello's push-forward formula.
