Non-Perturbative Yang-Mills from Supersymmetry and Strings, Or, in the Jungles of Strong Coupling

Abstract

I summarize some recent developments in the issue of planar equivalence between supersymmetric Yang-Mills theory and its orbifold/orientifold daughters. This talk is based on works carried out in collaboration with Adi Armoni, Sasha Gorsky and Gabriele Veneziano.Comment: Based on talks delivered at Planck-05/Mohapatra-Fest, ICTP, Trieste, May 23-28, 2005, and PASCOS-05, Gyeongju, Korea, May 30 - June 4, and the Cracow School of Theoretical Physics, Zakopane, Poland, June 3-12, 2005. 24 pages, 6 figure
