Two constructions of the isomonodromic tau-function

Two constructions of the isomonodromic tau-function are described. One uses F-manifold techniques to describe the tau-function related to the Frobenius manifold structure on the orbit spaces C^n/W, where W is a Coxeter group. The second uses Riemann surface techniques, in particular, properties of the prime-form, to construct the tau-function related to the Frobenius manifold structure on Hurwitz spaces.
