Compactification, Geometry and Duality: N=2
These are notes based on lectures given at TASI99. We review the geometry of the moduli space of N=2 theories in four dimensions from the point of view of superstring compactification. The cases of a
The Type I D instanton and its M theory origin
The tree-level amplitude for the scattering of two gauge particles constrained to move on the two distinct boundaries of eleven-dimensional space-time in the Horava-Witten formulation of M-theory is
Centralizers of Commuting Elements in Compact Lie Groups
The moduli space for a flat G-bundle over the two-torus is completely determined by its holonomy representation. When G is compact, connected, and simply connected, we show that the moduli space is


The semispin groups in string theory
In string theory, an important role is played by certain Lie groups which are locally isomorphic to SO(4m), m⩽8. It has long been known that these groups are actually isomorphic not to SO(4m) but
Disconnected forms of the standard group
Recent work in quantum gravity has led to a revival of interest in the concept of disconnected gauge groups. Here we explain how to classify all of the (nontrivial) groups which have the same Lie
Timelike Hopf duality and type IIA* string solutions
The usual T-duality that relates the type IIA and IIB theories compactified on circles of inversely related radii does not operate if the dimensional reduction is performed on the time direction
T-duality can fail
We show that T-duality can be broken by non-perturbative effects in string coupling. The T-duality in question is that of the 2-torus when the heterotic string is compactified on K3 × T2. This case
K3 Surfaces and String Duality
The primary purpose of these lecture notes is to explore the moduli space of type IIA, type IIB, and heterotic string compactified on a K3 surface. The main tool which is invoked is that of string
Metric symmetries and spin asymmetries of Ricci-flat Riemannian manifolds
The Calabi–Yau and Joyce manifolds used in string and M-theory compactifications have no continuous groups of isometries, but they often have nontrivial discrete (actually finite) isometry groups.
