Prym varieties and projective structures on Riemann surfaces
Indranil Biswas, Alessandro Ghigi, Luca Vai
Given an étale double covering of compact Riemannsurfaces with of genus at least two, we use the Prym variety of the cover to cons…

On the projective structures given by theta
Indranil Biswas, Luca Vai
Given a compact Riemann surface , the line in orthogonal to the sections vanishing at produces a natural projective structure on . We investigate the pro…

Theta functions and projective structures
Indranil Biswas, Alessandro Ghigi, Luca Vai
Given a compact Riemann surface , we consider the line, in the space of sections of on , orthogonal to all the sections that vanish at the origin. This line produce…
