On world-volume supersymmetry of supermembrane action in static gauge
Arkady A. Tseytlin, Zihan Wang
We review and elaborate on the issue of 3d world volume supersymmetry that appears as a residual part of global target space supersymmetry in the BST supermembrane action. While th…
Duality and Dilaton
A. A. Tseytlin
We review and elaborate on the issue of the dilaton transformation under the usual target space duality and its non-static generalization (or -model duali…
Strong coupling expansion of BPS Wilson loop in SYM theory and 2-loop Green-Schwarz string in AdSS
Matteo Beccaria, Stefan A. Kurlyand, Arkady A. Tseytlin
The exact localization result for the expectation value of the BPS circular Wilson loop in SYM theory is given in the planar limit by the famous Bessel func…
Renormalization Group and String Loops
Arkady A. Tseytlin
Fixed points of the 2d renormalization group flow are known to correspond to tree level string vacua. We discuss how the renormalization group (or "sigma model") approach can be ex…
Sigma model approach to string theory
Arkady A. Tseytlin
A review of the -model approach to derivation of effective string equations of motion for the massless fields is presented. We limit our consideration to the case of the tree a…
2-loop free energy of M2 brane in AdS S and surface defect anomaly in (2,0) theory
Matteo Beccaria, Stefan A. Kurlyand, Arkady A. Tseytlin
A -BPS surface operator viewed as a conformal defect in rank 6d (2,0) theory is expected to have a holographic description in terms of a probe M2 brane wrapped on…
