Abstract:
We define and explicitly calculate the tau-functions on different strata of spaces of Abelian
and quadratic differentials. This provides a machinery to calculate the determinants of Laplacians in flat metrics with conical singularities on Riemann surfaces. The results can be considered as a generalization of the
famous Kronecker formula for the Laplacian in the flat metric on an elliptic surface to the case of higher genus.
