A Pair of Calabi-Yau manifolds as an exactly soluble superconformal theory
TL;DR: In this paper, the prepotentials and geometry of the moduli spaces for a Calabi-Yau manifold and its mirror were derived and all the sigma model corrections to the Yukawa couplings and moduli space metric were obtained.
Journal ArticleDOI
Comments on Conifolds
Philip Candelas,Xenia de la Ossa +1 more
TL;DR: In this paper, the Ricci-flat Kahler metric is calculated in the vicinity of the nodes for the conifold, the resolution and the deformation, and it is shown that, owing to a topological obstruction, the manifold obtained as the result of independently resolving and deforming the nodes of a conifolds in general cannot be Kahler.
Journal ArticleDOI
Moduli Space of {Calabi-Yau} Manifolds
Philip Candelas,Xenia de la Ossa +1 more
TL;DR: The local geometry of the parameter space of Calabi-Yau manifolds has been studied in this paper, where it is shown that the parameters of the complex structure decompose into a product with the space of parameters as one factor and a complex extension of the Kahler class as the other.
Journal ArticleDOI
Duality symmetries from non-abelian isometries in string theory
TL;DR: In this article, the authors generalize this duality transformation to background with non-abelian isometries and show that this new transformation maps spaces with nonabelians to spaces that may have no isometria at all.
Journal ArticleDOI
Duality Symmetries from Non--Abelian Isometries in String Theories
TL;DR: In this article, the authors generalize this duality transformation to background with non-abelian isometries and show that it can be used to generate new solutions of the leading order string equations.
