We continue our review of Witten’s paper “Instantons and the Large N=4 Algebra”. We discuss the realization of large N=4 supersymmetry in the context of supersymmetric sigma-models, and discuss and motivate string theoretic duals to these sigma models. This talk aims to supply physical insight building on Saman’s talk from last week 2/17
