New Perspectives on the Quest for Unification
Edward Witten
Synthesizing older ideas about the 1/N expansion in gauge theory, the quantum mechanics of black holes, and quantum field theory in Anti de Sitter space, a new correspondence betwe…
Dibaryons, Branes, And Strings In AdS Orbifold Models
Sergei Gukov, Mukund Rangamani, Edward Witten
A generalization of the Maldacena conjecture asserts that Type IIB string theory on is equivalent to a certain supersymmetric gauge theory with bifundamental m…
D-Branes And K-Theory
Edward Witten
By exploiting recent arguments about stable nonsupersymmetric D-brane states, we argue that D-brane charge takes values in the K-theory of spacetime, as has been suspected before.…
Anti-de Sitter Space and the Center of the Gauge Group
Ofer Aharony, Edward Witten
Upon compactification on a circle, SU(N) gauge theory with all fields in the adjoint representation acquires a global symmetry because the center of the gauge group is .…
Superconformal Field Theory on Threebranes at a Calabi-Yau Singularity
Igor R. Klebanov, Edward Witten
Just as parallel threebranes on a smooth manifold are related to string theory on , parallel threebranes near a conical singularity are related to string the…
Theta Dependence In The Large N Limit Of Four-Dimensional Gauge Theories
Edward Witten
The theta dependent of pure gauge theories in four dimensions can be studied using a duality of large N gauge theories with string theory on a certain spacetime. Via this duality,…
