Gauge Symmetries on -Deformed Spaces
Rabin Banerjee, Saurav Samanta
A Hamiltonian formulation of gauge symmetries on noncommutative ( deformed) spaces is discussed. Both cases- star deformed gauge transformation with normal coproduct and undefor…
Gauge Theories on de Sitter space and Killing Vectors
Rabin Banerjee
We provide a general method for studying a manifestly covariant formulation of -form gauge theories on the de Sitter space. This is done by stereographically projecting the corr…
Gauge Generators, Transformations and Identities on a Noncommutative Space
Rabin Banerjee, Saurav Samanta
By abstracting a connection between gauge symmetry and gauge identity on a noncommutative space, we analyse star (deformed) gauge transformations with usual Leibnitz rule as well a…
Normal ordering and noncommutativity in open bosonic strings
Biswajit Chakraborty, Sunandan Gangopadhyay, Arindam Ghosh Hazra
Noncommutativity in an open bosonic string moving in the presence of a background Neveu-Schwarz two-form field is investigated in a conformal field theory approach, leadin…
Remarks on the Noncommutative Gravitational Quantum Well
Rabin Banerjee, Binayak Dutta Roy, Saurav Samanta
A planar phase space having both position and momentum noncommutativity is defined in a more inclusive setting than that considered elsewhere. The dynamics of a particle in a gravi…
Deformed relativistic and nonrelativistic symmetries on canonical noncommutative spaces
Rabin Banerjee, Kuldeep Kumar
We study the general deformed conformal-Poincare (Galilean) symmetries consistent with relativistic (nonrelativistic) canonical noncommutative spaces. In either case we obtain defo…
