Deformed Reissner--Nordstrom solutions in noncommutative gravity
Pradip Mukherjee, Anirban Saha
The leading order corrections to Reissner--Nordstrom solutions of the Einstein's equations on noncommutative space time have been worked out basing on a noncommutative gauge theory…
Gauge invariances vis-{á}-vis Diffeomorphisms in second order metric gravity: A new Hamiltonian approach
Pradip Mukherjee, Anirban Saha
A new analysis of the gauge invariances and their unity with diffeomorphism invariances in second order metric gravity is presented which strictly follows Dirac's constrained Hamil…
Lie algebraic Noncommutative Gravity
Rabin Banerjee, Pradip Mukherjee, Saurav Samanta
We exploit the Seiberg -- Witten map technique to formulate the theory of gravity defined on a Lie algebraic noncommutative space time. Detailed expressions of the Seiberg -- Witte…
Noncommutativity in interpolating string: A study of gauge symmetries in noncommutative framework
Sunandan Gangopadhyay, Arindam Ghosh Hazra, Anirban Saha
A new Lagrangian description that interpolates between the Nambu--Goto and Polyakov version of interacting strings is given. Certain essential modifications in the Poission bracket…
