We show that there is an infinite class of partition functions with world-sheet metric, space-time coordinates and first order systems, that correspond to volume forms on the moduli space of Riemann surfaces and are free of singularities at the Deligne-Mumford boundary. An example is the partition function with 4 = 2(c2 + c3 + c4 − c5) space-time coordinates, a b-c system of weight 3, one of weight 4 and a β-γ system of weight 5. Such partition functions are derived from the mapping of the Mumford forms to non-factorized scalar forms on Mg introduced in arXiv:1209.6049.

Abstract
We show that there is an infinite class of partition functions with world-sheet metric, space-time coordinates and first order systems, that correspond to volume forms on the moduli space of Riemann surfaces and are free of singularities at the Deligne-Mumford boundary. An example is the partition function with 4 = 2(c2 + c3 + c4 − c5) space-time coordinates, a b-c system of weight 3, one of weight 4 and a β-γ system of weight 5. Such partition functions are derived from the mapping of the Mumford forms to non-factorized scalar forms on Mg introduced in arXiv:1209.6049.File in questo prodotto:
