New properties of the intersection numbers on moduli spaces of curves
New properties intersection numbers moduli spaces curves
2018/4/20
We present certain new properties about the intersection numbers on moduli spaces of curves $\overline{\sM}_{g,n}$, including a simple explicit formula of $n$-point functions and several new identitie...
Moduli Stabilization with String Gas and Fluxes
String Gas Cosmology Model String Phenomenology moduli stabilization
2018/4/20
The question of how to stabilize all of the modulus fields coming from compactifications of string theory on internal manifolds is one of the outstanding challenges for string cosmology. Here, in the ...
Real Aspects of the Moduli Space of Genus Zero Stable Maps
Moduli space of genus zero stable maps real variety real structure
2010/2/26
We show that the moduli space of genus zero stable maps is a real projective variety if the target space is a smooth convex real projective variety. We show that evaluation maps, forgetful maps are re...
GEOMETRIC ASPECTS OF THE MODULI SPACE OF RIEMANN SURFACES
Introduction The Topological Aspects Moduli Space Background of the Teichm¨uller Theory
2018/4/20
The study of moduli space and Teichm¨uller space has a long history. These two spaces lie in the intersections of the researches in many areas of mathematics and physics. Many deep results have been o...
Canonical Metrics on the Moduli Space of Riemann Surfaces II
Canonical Metrics Moduli Space Riemann Surfaces
2018/4/20
In this paper we continue our study on the canonical metrics on the Teichm\"uller and the moduli space of Riemman surfaces. We first prove the equivalence of the Bergman metric and the Carath\'eodory ...
Canonical Metrics on the Moduli Space of Riemann Surfaces I
Introductions The Weil-Petersson metric Ricci metric its curvature
2018/4/20
One of the main purpose of this paper is to compare those well-known canonical and complete metrics on the Teichm¨uller and the moduli spaces of Riemann surfaces. We use as bridge two new metrics, the...
Shafarevich's Conjecture for CY Manifolds I (Moduli of CY Manifolds)
Shafarevich's Conjecture CY Manifolds I
2018/4/20
In this paper we study the moduli spaces related to CY manifolds. We apply the results of this paper to the following problem. Let C be a fixed Riemann surface with fixed finite points on it. Fix the ...
Calabi-Yau Threefolds and Moduli of Abelian Surfaces I
Calabi-Yau Threefolds Moduli of Abelian Surfaces I
2010/10/29
We describe birational models and decide the rationality/unirationality of moduli spaces AA_{d} (and AA^{lev}_{d}) of (1,d)-polarized abelian surfaces (with canonical level structure, respectively) f...
Collapsing D-Branes in Calabi-Yau Moduli Space: I
Collapsing D-Branes Calabi-Yau Moduli Space
2010/11/2
We study the quantum volume of D-branes wrapped around various cycles in Calabi-Yau manifolds, as the manifold's moduli are varied. In particular, we focus on the behaviour of these D-branes near phas...

New moduli spaces pointed curves pencils flat connections
2010/10/29
It is well known that formal solutions to the Associativity Equations are the same as cyclic algebras over the homology operad $(H_*(\bar{M}_{0,n+1}))$ of the moduli spaces of $n$--pointed stable cur...
