Short Distance Repulsive Gravity as a Consequence of Non Trivial PPN Parameters and
S. Kalyana Rama, Sasanka Ghosh
We look for a graviton-dilaton theory which can predict non trivial values of the PPN parameters and/or for a charge neutral point star, without any naked singularity. With…
N = 2 Super Algebra and its Nonlinear Realization Through Super KP Formulation
Sasanka Ghosh, Samir K. Paul
A nonlinear realization of super algebra is shown to exist through a consistent superLax formulation of super KP hierarchy. The reduction of the superLax operator give…
The Hamiltonian Structures of the super KP hierarchy Associated with an Even Parity SuperLax Operator
J. Barcelos-Neto, Sasanka Ghosh, Shibaji Roy
We consider the even parity superLax operator for the supersymmetric KP hierarchy of the form and obtain the two Hamiltonian structur…
KDV Hierarchy and its Nonpolynomial Realization Through Kac-Moody Currents
Sasanka Ghosh, Samir K. Paul
It is shown that KdV hierarchy can be expressed as definite nonpolynomials in Kac Moody currents and their derivatives by the action of Borel subgroup of on the…
