Exact S matrices and extended supersymmetry
E. Abdalla, M. C. B. Abdalla
In this revised version we correct some mistakes, realizing the supersymmetry algebra on the exact S matrix, taking into account several phase factros. We study the constraint impo…
The Algebra of Non-Local Charges in Non-Linear Sigma Models
E. Abdalla, M. C. B. Abdalla, J. C. Brunelli +1
We obtain the exact Dirac algebra obeyed by the conserved non-local charges in bosonic non-linear sigma models. Part of the computation is specialized for a symmetry group .…
On the Dirac Quantization of two Dimensional Gravity
M. C. B. Abdalla, F. P. Devecchi, E. Abdalla
We discuss the Dirac quantization of two dimensional gravity with bosonic matter fields. After defining the extended Hamiltonian it is possible to fix the gauge completely. The com…
Correlators in non-critical superstrings including the spinor emission vertex
D. Dalmazi, E. Abdalla
We discuss the structure of correlators involving the spinor emission vertex in non critical superstring theory. The technique used in the computation is the zero mode integr…
Off critical current algebras
E. Abdalla, M. C. B. Abdalla, G. Sotkov +1
We discuss the infinite dimensional algebras appearing in integrable perturbations of conformally invariant theories, with special emphasis in the structure of the consequent non-a…
String inspired effective Lagrangian and Inflationary Universe
E. Abdalla, A. C. V. V. de Siqueira
We consider a string inspired effective Lagrangian for the graviton and dilaton, containing Einstein gravity at the zero slope limit. The numerical solution of the problem shows as…
