Cylindrical symmetry locally isometric spacetime
Faizuddin Ahmed, Davood Momeni, Debojit Sarma +2
We present a maximally symmetric vacuum spacetime, which is locally isometric anti- de Sitter, admitting closed timelike curves appear after a definite instant of time i.e., a time…

Constructing a Supersymmetric Integrable System from the Hirota Method in Superspace
Debojit Sarma
An N=1 supersymmetric system is constructed and its integrability is shown by obtaining three soliton solutions for it using the supersymmetric version of Hirota's direct method.

Bilinearization of Supersymmetric KP Hierarchies Associated with Non-Trivial Flows
Sasanka Ghosh, Debojit Sarma
We show that the supersymmetric KdV and KP equations, related to the non-trivial flows, can be cast in the Hirota bilinear form. The existence of one, two and subsequently -soli…
