Green-Schwarz superstring action for (p,q)-strings from a wrapped supermembrane on a 2-torus

We consider a wrapped supermembrane around non-trivial two cycles of a 2-torus. We examine the double dimensional reduction and the T-dual transformation to deduce Green-Schwarz type IIB superstring action for (p,q)-strings directly from the wrapped supermembrane on the 2-torus. The resulting action has the couplings with both the NSNS- and the RR-background fields and has the tension of the (p,q)-string.

(p,q)-string in matrix-regularized membrane and type IIB duality

We consider a lightcone wrapped supermembrane compactified on 2-torus in the matrix regularization. We examine the double dimensional reduction technique and deduce the free matrix string of (p,q)-string in type IIB superstring theory explicitly from the matrix-regularized wrapped supermembrane. In addition we obtain the (2+1)-dimensional super Yang-Mills action in curved background. We also examine the duality.

(p,q)-string in the wrapped supermembrane on 2-torus -- A classical analysis of the bosonic sector --

We consider a wrapped supermembrane on $\R^9\times T^2$. We examine a double dimensional reduction to deduce a $(p,q)$-string in type IIB superstring theory from the wrapped supermembrane. In particular, directly from the wrapped supermembrane action, we explicitly derive the action of a string which carries the RR 2-form charge as well as the NSNS 2-form charge, and the tension of the string agrees with the $(p,q)$-string tension.
