چکیده
∗∗ Local and global properties of the moduli space of Calabi–Yau type compactifications determine the low energy parameters of the string effective action. We show that the moduli space geometry is entirely encoded in the Picard–Fuchs equations for the periods of the Calabi– Yau H–cohomology. ∗ Supported in part by DOE grants DE-AC0381-ER500050, DOE-AT03-88ER40384, task E and by MURST.

Duality Symmetries and Topology Change in String Theory
Duality symmetries for strings moving in non-trivial spacetime backgrounds are analysed. It is shown that for backgrounds generated from WZW and coset CFT models such duality symmetries are exact to all orders in string perturbation theory. Their implications for string dynamics in non-trivial/singular spacetimes are discussed. CERN-TH.7003/93 September 1993 ∗ Talk given at the EPS 93 Conferenc...
متن کاملK3–Fibrations and Heterotic-Type II String Duality
We analyze the map between heterotic and type II N=2 supersymmetric string theories for certain two and three moduli examples found by Kachru and Vafa. The appearance of elliptic j-functions can be traced back to specializations of the Picard-Fuchs equations to systems for K3 surfaces. For the three-moduli example we write the mirror maps and Yukawa couplings in the weak coupling limit in terms...
متن کاملThe Dual Faces of String
Duality symmetries for strings moving in non-trivial spacetime backgrounds are analysed. It is shown that, for backgrounds generated from compact WZW and coset models, such duality symmetries are exact to all orders in string perturbation theory. A global treatment of duality symmetries is given, by associating them to the known symmetries of affine current algebras ( affine-Weyl group and exte...
متن کاملPrepotentials from Symmetric Products
We investigate the prepotential that describes certain F 4 couplings in eight dimensional string compactifications, and show how they can be computed from the solutions of inhomogenous differential equations. These appear to have the form of the Picard-Fuchs equations of a fibration of Sym(K3) over IP. Our findings give support to the conjecture that the relevant geometry which underlies these ...
متن کاملGkz Hypergeometric Systems and Applications to Mirror Symmetry
Mirror symmetry of Calabi-Yau manifolds is one of the most beautiful aspects of string theory. It has been applied with great success to do non-perturbative calculation of quantum cohomology rings1−10. More recently, new ideas have been developed to apply mirror symmetry to study the moduli space of the type II string vacua compactified on a Calabi-Yau manifold. Some of the recent work on verif...
