Torelli Theorem for the Moduli Spaces of Connections on a Riemann Surface

چکیده

Let (X , x0) be any one–pointed compact connected Riemann surface of genus g, with g ≥ 3. Fix two mutually coprime integers r > 1 and d. Let MX denote the moduli space parametrizing all logarithmic SL(r, C)–connections, singular over x0, on vector bundles over X of degree d. We prove that the isomorphism class of the variety MX determines the Riemann surface X uniquely up to an isomorphism, although the biholomorphism class of MX is known to be independent of the complex structure of X . The isomorphism class of the variety MX is independent of the point x0 ∈ X . A similar result is proved for the moduli space parametrizing logarithmic GL(r, C)–connections, singular over x0, on vector bundles over X of degree d.

TORELLI THEOREM FOR MODULI SPACES OF SL(r,C)–CONNECTIONS ON A COMPACT RIEMANN SURFACE

Let X be any compact connected Riemann surface of genus g, with g ≥ 3. For any r ≥ 2, let MX denote the moduli space of holomorphic SL(r, C)–connections over X . It is known that the biholomorphism class of the complex variety MX is independent of the complex structure of X . If g = 3, then we assume that r ≥ 3. We prove that the isomorphism class of the variety MX determines the Riemann surfac...

Torelli Theorem for the Deligne–hitchin Moduli Space

Fix integers g ≥ 3 and r ≥ 2, with r ≥ 3 if g = 3. Given a compact connected Riemann surface X of genus g, letMDH(X) denote the corresponding SL(r, C) Deligne–Hitchin moduli space. We prove that the complex analytic space MDH(X) determines (up to an isomorphism) the unordered pair {X, X}, where X is the Riemann surface defined by the opposite almost complex structure on X .

Residue Theorem for Rational Trigonometric Sums and Verlinde’s Formula

We present a compact formula computing rational trigonometric sums. Such sums appeared in the work of E. Verlinde on the dimension of conformal blocks in WessZumino-Witten (WZW) theory. As an application, we show that a formula of J.-M. Bismut and F. Labourie for the Riemann-Roch numbers of moduli spaces of flat connections on a Riemann surface coincides with Verlinde’s expression.

Relations among Fixed Points

Let M be a smooth manifold with a circle action, and {P } be the fixed point sets. The problem I want to discuss in this paper is how to get the topological information of one relatively complicated fixed point set, say P 0 , from the other much simpler fixed points. Such problems are interesting in symplectic geometry and geometric invariant theory, especially in the study of moduli spaces. In...

A Riemann–Hilbert approach to Painlevé IV

The methods of [vdP-Sa, vdP1, vdP2] are applied to the fourth Painlevé equation. One obtains a Riemann– Hilbert correspondence between moduli spaces of rank two connections on P1 and moduli spaces for the monodromy data. The moduli spaces for these connections are identified with Okamoto–Painlevé varieties and the Painlevé property follows. For an explicit computation of the full group of Bäckl...
