  1. Moduli Space of (0,2) Conformal Field Theories

    Bertolini, Marco2016

    … a conjecture for a toric structure of the SCFT moduli space in a large class of models. In the final part, we study the stability of heterotic compactifications described by (0,2) GLSMs with respect to worldsheet instanton corrections to the space-time superpotential following the work of …

  2. Towards birational aspects of moduli space of curves

    Dwivedi, Shashank S. (Shashank Shekhar)Massachusetts Institute of Technology2010

    The moduli space of curves has proven itself a central object in algebraic geometry. The past decade has seen substantial progress in understanding its geometry. This has been spurred by a flurry of ideas from geometry (algebraic, symplectic, and differential), topology, combinatorics, and physics. …

Extended Burniat surfaces with K^2=3 were constructed by Bauer and Catanese in the course of studying the tertiary Burniat surfaces and they showed that their closure is an irreducible component of the moduli space. We prove here the …

We show how to use this strategy to explicitly compute the distribution in the case of the octagon, the first case where the Veech group has multiple cusps, how to generalize the construction …

We prove that for large 1, X has a unique irreducible component of maximal dimension, consisting of the hypersurfaces singular along a linear …

  6. A compact moduli space for Cohen-Macaulay curves in projective space

    Hønsen, Morten Oskar, 1973-Massachusetts Institute of Technology2004

    We define a moduli functor parametrizing finite maps from a projective (locally) Cohen-Macaulay curve to a fixed projective space. The definition of the functor includes a number of technical conditions, but the most important is that the map is almost everywhere an isomorphism onto its image. The …

  8. Large genus bounds for the distribution of triangulated surfaces in moduli space

    Vasudevan, SahanaMassachusetts Institute of Technology2022

    … how triangulated surfaces are distributed in the moduli space of Riemann surfaces as the genus tends to infinity. Mirzakhani raised this question in her 2010 ICM address. We show that in the large genus case, triangulated surfaces are well distributed in moduli space in a fairly strong sense. We …

The topology of moduli spaces of planar quadrilaterals (the set of all distinct planar quadrilaterals with fixed side lengths) has been well-studied [5], [8], [10]. The symplectic geometry of these spaces has been …

  14. Bubble tree compactification of instanton moduli spaces

    Qiao, Shuaige2021

    We study the compactification of moduli spaces defined by the anti-self-dual (ASD) Yang-Mills equations on SU(2) or SO(3) bundles over closed oriented Riemannian 4-manifolds and 4-orbifolds. In general the ASD moduli space is not compact since the curvature of a sequence of connections may blow up …

    Bleier, Thomas S.

    In the moduli space of curves of genus 3, the locus of hyperelliptic curves forms a divisor, that is a closed subscheme of codimension 1. J. Harris and I. Morrison compute an expression for the class of this divisor, in the Chow ring of the moduli space, using a map of vector bundles and by …
