Holomorphic Couplings In Non-Perturbative String Compactifications
In this thesis we present an analysis of several aspects of four-dimensional, non-perturbative N = 1 compactifications of string theory. Our focus is on the study of brane dynamics and their effective physics as encoded in the holomorphic couplings of the low-energy N = 1 effective action, most prominently the superpotential W . The thesis is divided into three parts. In part one we derive the ...
متن کاملN = 1 String Duality
We discuss duality between Type IIA string theory, eleven-dimensional supergravity, and heterotic string theory in four spacetime dimensions with N = 1 supersymmetry. We find theories whose infrared limit is trivial at enhanced symmetry points as well as theories with N = 1 supersymmetry but the field content of N = 4 theories which flow to the N = 4 fixed line in the infrared.
متن کاملAspects of Duality in N = 2 String Vacua ⋆
We collect further evidence for the proposed duality between N = 2 heterotic and type II string vacua in a specific model suggested by Kachru and Vafa. In the gauge sector the previous analysis is extended; it is further shown that the duality also holds for the one–loop gravitational couplings to the vector multiplets. ⋆ Research supported in part by: the NSF, under grant PHY–90–09850 (V.K.); ...
متن کاملTopological Partition Function and String-String Duality
The evidence for string/string-duality can be extended from the matching of the vector couplings to gravitational couplings. In this note this is shown in the rank three example, the closest stringy analog of the Seiberg/Witten-setup, which is related to the Calabi-Yau WP 4 1,1,2,2,6(12). I provide an exact analytical verification of a relation checked by coefficient comparison to fourth order ...
متن کاملM-Theory and String-String Duality
In this article we examine the compatibility of some recent results, results relating M-Theory to String Theory, with the string-string duality conjecture in six-dimensions. In particular, we rederive the relation between M-Theory and Type IIA strings. We then go on to examine in detail M-Theory on K3× S and its relation to the Heterotic theory on T . We conclude with some remarks on M-Theory o...
