Moduli of Vector Bundles on Curves in Positive Characteristics
Kirti Joshi, Eugene Z. Xia
Let X be a projective curve of genus 2 over an algebraically closed field of characteristic 2. The Frobenius map on X induces a rational map on the moduli scheme of rank-2 bundles.…

The Moduli of Flat U(p,1) Structures on Riemann Surfaces
Eugene Z. Xia
For a compact Riemann surface of genus , $\Hom(π_1(X), U(p,1))/U(p,1)$ is the moduli space of flat $\U(p,1)$-connections on . There is an integer invariant, , the…
