Integral Riemann-Roch formulae for cyclic subgroups of mapping class groups
arXiv:math/0612380
Abstract
The first author conjectured certain relations for Morita-Mumford classes and Newton classes in the integral cohomology of mapping class groups (integral Riemann-Roch formulae). In this paper, the conjecture is verified for cyclic subgroups of mapping class groups.
