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...
