Every K3 surface is Kählerian, i.e., admits a Kähler metric (Siu). Any two smooth K3 surfaces are deformation equivalent, hence diffeomorphic (Kodaira). The moduli space of holomorphic structures on a K3 surface is $20$-dimensional, and admits a branched covering by a ball in $\Cpx^{20}$ (Siu). The PI will investigate the following projects, all of which emerge from the study of the algebraic/analytic aspects of the moduli spaces. First, he will study the geometry of the moduli space of polarized Kahler manifolds via algebraic and analytic means (e.g., the positivity of the line bundles and heights over the moduli space).

Let P be a smooth principal G-bundle over M. For simplicity we assume that the Lie group G=SU(n), n^2. An St/^-connection A on P is called self.

This book discusses as well the natural compactification of the moduli space of polarized Einstein–Kähler orbitfold with a given Hilbert polynomials. The final chapter deals with solving a degenerate Monge–Ampère equation by constructing a family of Einstein–Kähler metrics on the smooth part of minimal varieties of general kind.

Mcmullen. stable vector bundles on a K3-surface with hyper-Kahler structure is given, and this metric is extended to the compactification of the moduli space by torsion-free sheaves. INTRODUCTION The moduli space of stable vector bundles on a compact Kahler surface (S, ω) has a canonical Kahler metric, which it is natural to call the Weil-Petersson.

There exists a Kahler metric on moduli space of Calabi-Yau varieties we call it again Weil Petersson metric and can be written as Ricci curvature of direct image of relative Line bundle. Fujiki-Schumacher considered the moduli space of Kahler manifolds admitting constant scalar curvature Kahler (cscK) metrics.

In these examples we compute the Kaehler class of the natural L^2-metric on the moduli space. In the simplest cases we compute the volume and total scalar curvature of the muduli space.

Finally, we note that for abelian GLSM the vortex moduli space is a compactification of the space of holomorphic maps from M to toric targets, just as in the. In fact by knowing this fact we can construct a canonical Weil-Petersson metric on moduli space of Kahler-Einstein Fano varieties with mild singularities aic-geometry complex-geometry moduli-spaces kahler-manifolds minimal-model-program.

This proportionality is an analogue of the Einstein field equation in general relativity. The following conjecture is due to E. Calabi: Let be a compact connected complex manifold and its first Chern class; then. a) if, then carries a unique (Ricci-negative) Kähler–Einstein metric such that.

b) if, then any Kähler class of admits a unique (Ricci-flat) Kähler–Einstein metric such. Let $\cM_{g,n}$ be the moduli space of Riemann surfaces of genus $g$ with $n$ punctures.

From a complex perspective, moduli space is hyperbolic. For example. For compact Riemann surfaces of genus at least two, using Petersson’s Hermitian pairing for automorphic forms, Weil introduced a Hermitian metric for the Teiclmüller space, now known as the Weil-Petersson metric.

Ahlfors [1,2] showed that the Weil-Petersson metric is Kähler and that its Ricci and holomorphic section curvatures are by: Abstract. Metric deformation methods are used to give a more geometric proof of the well known Calabi conjectures of Kahler geometry.

More precisely, it is proven that given any closed (1,1) form on a compact Kahler manifold M, which represents the first Chern class of M, one can deform the initial metric by certain Hamilton's type equation to the limit Kahler metric which has the given (1,1. Moduli spaces of sheaves of rank 2 on a surface are not smooth, unless we consider sheaves with special invariants on special surfaces.

Nevertheless, something is known about the type of singularities they can attain. Concerning the geometry of moduli spaces of sheaves of higher rank, there are two guiding principles for the investigation. ries and the Seiberg-Witten solution.

For local special geometry, we study their emergence in N = 2;d = 4 supergravity and Calabi-Yau moduli space. In particular, we discuss the connection between string eﬀective action and the metric on Calabi-Yau moduli space, and the non-renormalization theorem of type IIB complex moduli space.

The de nitions needed for the more general setting of Theorem 1’ will be given in Section 5. We remark that while Theorem 1’ covers the case of The. In these examples we compute the Kaehler class of the natural L^2-metric on the moduli space.

In the simplest cases we compute the volume and total scalar curvature of the muduli space. Finally, we note that for abelian GLSM the vortex moduli space is a compactification of the space of holomorphic maps from M to toric targets, just as in the Cited by: 4.

QUASI-PROJECTIVITY OF THE MODULI SPACE OF SMOOTH KAHLER-EINSTEIN FANO MANIFOLDS CHI LI, XIAOWEI WANG, AND CHENYANG XU Abstract. In this note, we prove that there is a canonical continuous Hermitian metric on the CM line bundle over the proper moduli space Mof smoothable K ahler-Einstein Fano varieties.

In the study of the moduli space Mg (and the Teichmüller space Tg) of compact Riemann surfaces of genus g >2, the Weil-Petersson metric plays an important role, and it has been widely studied. In particular, Ahlfors ([Ahl61], [Ahl62]) showed that the Weil-Petersson metric on Tg is a Kahler metric.
