S-Duality from OM-Theory
We study the compactification of OM-theory on tori and show a simple heuristic derivation of the S-duals of noncommutative open string theory in diverse dimensions from the OM-theoretical point of view. In particular, we identify the S-duality between noncommutative open string theory and noncommutative Yang-Mills theory in (3 + 1) dimensions as the exchange of two circles of a torus on which O...
متن کاملDuality and S-theory
1. Given topological spaces X and Fand two continuous mappings ƒ o and jfi from X to F (denoted by fo, fi : X—> F) we say that ƒ o is homotopic to jfi (denoted by fo—fi) if there exists a continuous family of continuous mappings ht: X—+Y for O^t^l such that ho=fo and h =/ i . Intuitively fo<^fi if the map ƒ o can be continuously deformed into the map jfi. I t is easily seen [4; 7] that the rela...
متن کاملS-duality in Abelian gauge theory revisited
Definition of the partition function of U(1) gauge theory is extended to a class of fourmanifolds containing all compact spaces and the asymptotically locally flat (ALF) ones including the multi-Taub–NUT sopaces. The partition function is calculated via zetafunction regularization and heat kernel techniques with special attention to its modular properties. In the compact case, compared with the...
متن کاملChern - Simons Theory and S - duality
We study S-dualities in analytically continued SL(2) Chern-Simons theory on a 3-manifold M . By realizing Chern-Simons theory via a compactification of a 6d five-brane theory on M , various objects and symmetries in Chern-Simons theory become related to objects and operations in dual 2d, 3d, and 4d theories. For example, the space of flat SL(2,C) connections on M is identified with the space of...
متن کاملS-Duality and Noncommutative Gauge Theory
It is conjectured that strongly coupled, spatially noncommutative N = 4 Yang-Mills theory has a dual description as a weakly coupled open string theory in a near critical electric field, and that this dual theory is fully decoupled from closed strings. Evidence for this conjecture is given by the absence of physical closed string poles in the non-planar oneloop open string diagram. The open str...
