M-Theory and Topological Strings--II
Rajesh Gopakumar, Cumrun Vafa
It is shown how the topological string amplitudes encode the BPS structure of wrapped M2 branes in M-theory compactification on Calabi-Yau threefolds. This in turn is related to a…

On the Gauge Theory/Geometry Correspondence
Rajesh Gopakumar, Cumrun Vafa
The 't Hooft expansion of SU(N) Chern-Simons theory on is proposed to be exactly dual to the topological closed string theory on the blow up of the conifold geometry. T…

M-Theory and Topological Strings--I
Rajesh Gopakumar, Cumrun Vafa
The terms of Type IIA strings on Calabi-Yau 3-folds, which are given by the corresponding topological string amplitudes (a worldsheet instanton sum for all genera),…
