Complex Multiplication Symmetry of Black Hole Attractors
Monika Lynker, Vipul Periwal, Rolf Schimmrigk
We show how Moore's observation, in the context of toroidal compactifications in type IIB string theory, concerning the complex multiplication structure of black hole attractor var…
String field theory, non-commutative Chern-Simons theory and Lie algebra cohomology
David J. Gross, Vipul Periwal
Motivated by noncommutative Chern-Simons theory, we construct an infinite class of field theories that satisfy the axioms of Witten's string field theory. These constructions have…
Deformation quantization as the origin of D-brane non-Abelian degrees of freedom
Vipul Periwal
I construct a map from the Grothendieck group of coherent sheaves to -homology. This results in explicit realizations of -homology cycles associated with D-brane configuratio…
D-brane charges and K-homology
Vipul Periwal
It is argued that D-brane charge takes values in K-homology. For smooth manifolds with spin structure, this could explain why the phase factor calculated with a D-brane stat…
Nonperturbative effects in deformation quantization
Vipul Periwal
The Cattaneo-Felder path integral form of the perturbative Kontsevich deformation quantization formula is used to explicitly demonstrate the existence of nonperturbative correction…
Schwinger-Dyson = Wheeler-DeWitt: gauge theory observables as bulk operators
Gilad Lifschytz, Vipul Periwal
We argue that the second-order gauge-invariant Schwinger-Dyson operator of a gauge theory is the Wheeler-DeWitt operator in the dual string theory. Using this identification, we co…
