Comments On String Theory
Edward Witten
String theory avoids the ultraviolet infinities that arise in trying to quantize gravity. It is also more predictive than conventional quantum field theory, one aspect of this bein…
Singularities in string theory
Edward Witten
String theory is a quantum theory that reproduces the results of General Relativity at long distances but is completely different at short distances. Mathematically, string theory…
Quest For Unification
Edward Witten
The GUT-based approach to physics has been attractive since it was first put forward close to thirty years ago; it has been enriched by new ideas, notably supersymmetry and strings…
Deconstruction, G_2 Holonomy, and Doublet-Triplet Splitting
Edward Witten
We describe a mechanism for using discrete symmetries to solve the doublet-triplet splitting problem of four-dimensional supersymmetric GUT's. We present two versions of the mechan…
Multi-Trace Operators, Boundary Conditions, And AdS/CFT Correspondence
Edward Witten
We argue that multi-trace interactions in quantum field theory on the boundary of AdS space can be incorporated in the AdS/CFT correspondence by using a more general boundary condi…
