Eleven Dimensional Superstring with New Supersymmetry and D=10 type 2A Green-Schwarz Superstring [PDF]
A covariant action for closed D=11 superstring with local $\kappa$-symmetry and global supersymmetry transformations obeying the algebra $\{Q_\alpha,Q_\beta\}=C\Gamma^{\mu\nu}P_\mu n_\nu$ is suggested. Physical sector variables of the model and their dynamics exactly coincide with those of the D=10 type IIA Green-Schwarz superstring.

Generalized Action Principle for superstrings and supermembranes [PDF]
Two approaches concerning the connection of the fermionic kappa -- symmetry with the superstring world -- sheet superdiffeomorphism transformations are discussed. The first approach is based on the twistor -- like formulation of the superstring action and the second one on a reformulation of the superstring and super~-~p~-~brane actions according to ...

Superstrings near the conformal boundary of AdS3
We study worldsheet sphere amplitudes, in the RNS formalism, in superstring theory on AdS3 × X with pure NS-NS flux using the near-boundary approximation.

On the cigar CFT and Schwarzschild horizons
Aspects of shock waves and instantly-created folded strings operators in the supersymmetric SL(2)k/U(1) CFT, and their relevance to the near-horizon physics of Schwarzschild black holes in perturbative superstring theory, are presented.

Finiteness of multi-loop superstring amplitudes [PDF]
Superstring amplitudes of an arbitrary genus are calculated through super-Schottky parameters by a summation over the fermion strings. For a calculation of divergent multi-loop fermion string amplitudes a supermodular invariant regularization procedure is used. A cancellation of divergences in the superstring amplitudes is established.

Hidden symmetries from extra dimensions
In Kaluza-Klein compactifications, some symmetries of the higher dimensional theory are preserved in lower dimensions, others are broken, and occasionally, there are symmetry enhancements.
