On the Duality between the Heterotic String and F-Theory in 8 Dimensions
Gabriel Lopes Cardoso, Gottfried Curio, Dieter Lust +1
In this note we compare the moduli spaces of the heterotic string compactified on a two-torus and F-Theory compactified on an elliptic K3 surface for the case of an unbroken E8 x E…
Perturbative Couplings and Modular Forms in N=2 String Models with a Wilson Line
Gabriel Lopes Cardoso, Gottfried Curio, Dieter Lust
We consider a class of four parameter D=4, N=2 string models, namely heterotic strings compactified on K3 times T2 together with their dual type II partners on Calabi-Yau three-fol…
Modular Symmetries of N=2 Black Holes
Gabriel Lopes Cardoso, Dieter Lust, Thomas Mohaupt
We discuss the transformation properties of classical extremal N=2 black hole solutions in S-T-U like models under S and T duality. Using invariants of (subgroups of) the triality…
Higher-Order Gravitational Couplings and Modular Forms in Heterotic String Compactifications
Bernard de Wit, Gabriel Lopes Cardoso, Dieter Lüst +2
The restrictions of target--space duality are imposed at the perturbative level on the holomorphic Wilsonian couplings that encode certain higher-order gravitational interactions i…
Instanton Numbers and Exchange Symmetries in Dual String Pairs
Gabriel Lopes Cardoso, Gottfried Curio, Dieter Lüst +1
In this note, we comment on Calabi-Yau spaces with Hodge numbers and . We focus on the Calabi-Yau space and show how some of its inst…
