Chiral Fermions from Manifolds of Holonomy
Bobby Acharya, Edward Witten
M-theory compactification on a manifold X of holonomy can give chiral fermions in four dimensions only if X is singular. A number of examples of conical singularities that gi…
Conformal Operators for Partially Massless States
Louise Dolan, Chiara R. Nappi, Edward Witten
The AdS/CFT correspondence is explored for ``partially massless'' fields in AdS space (which have fewer helicity states than a massive field but more than a conventional massless f…
Anomaly Cancellation On Manifolds Of G_2 Holonomy
Edward Witten
Smooth manifolds of G_2 holonomy, used to compactify M-theory to four dimensions, give only abelian gauge groups without charged matter multiplets. But singular G_2-manifolds can g…
M-Theory Dynamics On A Manifold Of G_2 Holonomy
Michael Atiyah, Edward Witten
We analyze the dynamics of M-theory on a manifold of G_2 holonomy that is developing a conical singularity. The known cases involve a cone on CP^3, where we argue that the dynamics…
Quantum Gravity In De Sitter Space
Edward Witten
We discuss some general properties of quantum gravity in De Sitter space. It has been argued that the Hilbert space is of finite dimension. This suggests a macroscopic argument tha…
Anomaly Analysis of Brane-Antibrane Systems
John H. Schwarz, Edward Witten
String theories with branes can often be generalized by adding brane-antibrane pairs. We explore the cancellation of anomalies in this more general context, extending the familiar…
