Factorization of point configurations, cyclic covers, and conformal blocks
Factorization of point configurations, cyclic covers, and conformal blocks
We describe a relation between the invariants of n ordered points in projective d -space and of points contained in a union of two linear subspaces. This yields an attaching map for GIT quotients parameterizing point configurations in these spaces, and we show that it respects the Segre product of …
