Bosonization of a Topological Coset Model and Non-critical String Theory
We analyze the relation between a topological coset model based on super SL(2, R)/U(1) coset and non-critical string theory by using free field realization. We show that the twisted N = 2 algebra of the coset model can be naturally transformed into that of noncritical string. The screening operators of the coset models can be identified either with those of the minimal matters or with the cosmo...
متن کاملExtended Superconformal Algebras on AdS
We study a supersymmetric extension of the Virasoro algebra on the boundary of the anti-de Sitter space-time AdS3. Using the free field realization of the currents, we show that the world-sheet affine Lie superalgebras osp(1|2)(1), sl(1|2)(1) and sl(2|2)(1) provide the boundary N = 1, 2 and 4 extended superconformal algebras, respectively. The duality between the type IIB string theory on AdS3 ...

متن کاملYangian Symmetry of Scattering Amplitudes in N = 4 super Yang-Mills Theory
Tree-level scattering amplitudes in N = 4 super Yang-Mills theory have recently been shown to transform covariantly with respect to a ‘dual’ superconformal symmetry algebra, thus extending the standard superconformal symmetry algebra psu(2, 2|4) of the theory. In this paper we derive the action of the dual superconformal generators in on-shell superspace and extend the dual generators suitably ...
متن کاملMore Super Schrödinger Algebras from Psu(2,2|4)
We discuss super Schrödinger algebras with less supercharges from N=4 superconformal algebra psu(2,2|4). Firstly N=2 and N=1 superconformal algebras are constructed from the psu(2,2|4) via projection operators. Then a super Schrödinger subalgebra is found from each of them. The one obtained from N=2 has 12 supercharges with su(2)2×u(1) and the other from N=1 has 6 supercharges with u(1) . By co...
