Abstract:
We give an effective algorithm to compute the Euler characteristics $\chi (\overline {\mathcal {M}}_{1,n}, \bigotimes _{i=1}^n L_i^{ d_i})$. This work is a sequel to the 1997 work of the first author.
In addition, we give a simple proof of Pandharipande’s vanishing theorem $H^j (\overline {\mathcal {M}}_{0,n}, \bigotimes _{i=1}^n L_i^{ d_i})=0$ for $j \ge 1, d_i \ge 0$.
