On Lagrangian formulation of Higher Spin Theories on AdS
A. Fotopoulos, K. L. Panigrahi, M. Tsulaia
In this short note we present a Lagrangian formulation for free bosonic Higher Spin fields which belong to massless reducible representations of D-dimensional Anti de Sitter group…
D-Brane solutions in a light-like linear dilaton background
Rashmi R. Nayak, Kamal L. Panigrahi
The light-like linear dilaton background presents a simple time dependent solution of type II supergravity equations of motion that preserves 1/2 supersymmetry in ten dimensions. W…
Time-dependent supergravity solutions in null dilaton background
Rashmi R. Nayak, Kamal L. Panigrahi, Sanjay Siwach
A class of time dependent pp-waves with NS-NS flux in type IIA string theory is considered. The background preserves 1/4 supersymmetry and may provide a toy model of Big Bang cosmo…
D1-brane with Overcritical Electric Field in AdS3 and S-brane
J. Kluson, Rashmi R. Nayak, Kamal L. Panigrahi
We study aspects of Dirichlet S-branes, which are defined as Dirichlet boundary condition on a time like embedding of open strings, in general backgrounds. By applying T-duality al…
