Almost-isometry between Teichmüller metric and length-spectra metric on moduli space
Teichm¨uller metric length-spectra metric almost isometry
2011/1/19
We prove an analogue of Farb-Masur’s theorem that the lengthspectra metric on moduli space is “almost isometric” to a simple model V(S) which is induced by the cone metric over the complex of curves. ...
By a mathematical instanton of charge n, we understand a rank-2 algebraic vector bundle E
on the 3-dimensional projective space P3 with Chern classes (1) c1(E) = 0, c2(E) = n,
satisfying the vanishi...
Scalar Moduli, Wall Crossing and Phenomenological Predictions
Wall Crossings Intrinsic Geometry Moduli Configurations
2011/3/2
We present the scalar moduli stabilization from the perspective of the real intrinsic
geometry.
We use the framework of Quot schemes to give a novel description of the moduli spaces of stable n-pairs, also interpreted as gauged vortices on a closed Riemann surface with target Matr×n(C), where ...
The rationality of the moduli spaces of trigonal curves of odd genus
trigonal curve rationality of moduli
2011/1/18
The moduli spaces of trigonal curves of odd genus g ≥ 5 are proven to be rational.
We show that the Brauer group of any moduli space of stable pairs with fixed determinant over a curve is zero.
Moduli of Galois p-covers in mixed characteristics
Moduli of Galois p-covers mixed characteristics
2010/12/9
Fix a prime number p. The aim of this paper is to define a complete moduli stack of degree-p covers Y → X, with Y a stable curve which is a G-torsor over X, for a suitable group scheme G/X. The curve ...
Enumerative and asymptotic analysis of a moduli space
Enumerative asymptotic analysis moduli space
2010/12/13
We study exact and asymptotic enumerative aspects of the Hilbert series of the cohomology
ring of the moduli space of stable pointed curves of genus zero. This manifold is related to the WDVV (Witten...
A note on the unirationality of a moduli space of double covers
Moduli spaces curves algebraic groups Chow groups
2010/12/10
In this note we look at the moduli space R3,2 of double covers of genus three curves, branched along 4 distinct points. This space was studied by Bardelli, Ciliberto and Verra in [BCV].
