A Path Integral Approach To Noncommutative Superspace
Iouri Chepelev, Calin Ciocarlie
A path integral formula for the associative star-product of two superfields is proposed. It is a generalization of the Kontsevich-Cattaneo-Felder's formula for the star-product of…
Non-Abelian Wilson Surfaces
Iouri Chepelev
A definition of non-abelian genus zero open Wilson surfaces is proposed. The ambiguity in surface-ordering is compensated by the gauge transformations.
Convergence Theorem for Non-commutative Feynman Graphs and Renormalization
Iouri Chepelev, Radu Roiban
We present a rigorous proof of the convergence theorem for the Feynman graphs in arbitrary massive Euclidean quantum field theories on non-commutative R^d (NQFT). We give a detaile…
Renormalization of Quantum Field Theories on Noncommutative R^d, I. Scalars
Iouri Chepelev, Radu Roiban
A noncommutative Feynman graph is a ribbon graph and can be drawn on a genus 2-surface with a boundary. We formulate a general convergence theorem for the noncommutative Feynma…
A note on correlation functions in AdS_5/SYM_4 correspondence on the Coulomb branch
Iouri Chepelev, Radu Roiban
We compute certain two-point functions in D=4, , SU(N) SYM theory on the Coulomb branch using SUGRA/SYM duality and find an infinite set of first order poles at masses…
Are M-atrix theory and Maldacena's conjecture related?
Iouri Chepelev
We give arguments in the support of a relation between M-atrix theory and Maldacena's conjecture. M-atrix theory conjecture implies the equivalence of 11-D light-cone supergravity…
