String Theory and Duality
Paul S. Aspinwall
This is a very brief survey of some results in the geometry of string duality delivered at a lecture given at ICM 1998, Berlin. String Duality is the statement that one kind of str…
The Heterotic String, the Tangent Bundle, and Derived Categories
Paul S. Aspinwall, Ron Y. Donagi
We consider the compactification of the E8xE8 heterotic string on a K3 surface with "the spin connection embedded in the gauge group" and the dual picture in the type IIA string (o…
Non-Simply-Connected Gauge Groups and Rational Points on Elliptic Curves
Paul S. Aspinwall, David R. Morrison
We consider the F-theory description of non-simply-connected gauge groups appearing in the E8 x E8 heterotic string. The analysis is closely tied to the arithmetic of torsion point…
Aspects of the Hypermultiplet Moduli Space in String Duality
Paul S. Aspinwall
A type IIA string (or F-theory) compactified on a Calabi-Yau threefold is believed to be dual to a heterotic string on a K3 surface times a 2-torus (or on a K3 surface). We conside…
