Seminar on Algebra, Geometry and Physics Inside the moduli space of stable curves there are closed

subsets defined by the condition that the curve C admits a finite cover

of a second curve D with specified ramification behavior. I will show

how these sets can be parametrized by nice smooth and proper moduli

spaces. In many cases, this parametrization can be used to compute the

fundamental class of such admissible cover loci in the cohomology group

of the moduli space. This is joint work with Jason van Zelm.
