Torelli theorem for moduli spaces of SL(r,C)-connections on a compact Riemann surface | | Indranil Biswas

20 Feb 2007 | | Subject: | Algebraic Geometry | | Abstract: | Let $X$ be any compact connected Riemann surface of genus $g geq 3$. For any $rgeq 2$, let $M_X$ denote the moduli space of holomorphic $SL(r,C)$-connections over $X$. It is known that the biholomorphism class of the complex variety $M_X$ is independent of the complex structure of $X$. If $g=3$, then we assume that $rgeq 3$. We prove that the isomorphism class of the variety $M_X$ determines the Riemann surface $X$ uniquely up to isomorphism. A similar result is proved for the moduli space of holomorphic $GL(r,C)$-connections on $X$.
We also show that the Torelli theorem remains valid for the moduli spaces of connections, as well as those of stable vector bundles, on geometrically irreducible smooth projective curves defined over the field of real numbers. | | Source: | arXiv, math/0702579 | | Services: | Forum | Review | PDF | Favorites | |
