dc.descriptionLet $X$ be a smooth projective curve of genus $g\geq 2$ over the complex numbers. Fix $n\geq 2$, and an integer $d$. A pair $(E,ϕ)$ over $X$ consists of an algebraic vector bundle $E$ of rank $n$ and degree $d$ over $X$ and a section $ϕ$. There is a concept of stability for pairs which depends on a real parameter $τ$. Let $M_τ(n,d)$ be the moduli space of $τ$-semistable pairs of rank $n$ and degree $d$ over $X$. We prove that the cohomology groups of $M_τ(n,d)$ are Hodge structures isomorphic to direct summands of tensor products of the Hodge structure $H^1(X)$. This implies a similar result for the moduli spaces of stable vector bundles over $X$.
