Query: Moduli spaces of anti-invariant vector bundles over a curve   Let $X$ be a smooth irreducible projective curve with an involution $\sigma$.
A vector bundle $E$ over $X$ is called anti-invariant if there exists an
isomorphism $\sigma^*E\rightarrow E^*$. In this paper, we give a construction
of the moduli spaces of anti-invariant vector bundles over $X$.
