Abstract

In this paper we modify our coordinate construction in “Coordinates for the Universal Moduli Space of Holomorphic Vector Bundles” [Travaux Math., XXV (2017), pp. 9–39] on the universal moduli space of pair consisting of a Riemann surfaces and a stable holomorphic bundles on the Riemann surface, so as to produce a new set of coordinates, which are in fact Kähler coordinates on this universal moduli space. Using our Kähler coordinates, we are able to give a functional determinant formula for the Ricci potential of the universal moduli space. As a corollary we compute the first Chern-class of the universal moduli space.
