Gauge Transformations, BRST Cohomology and Wigner's Little Group
R. P. Malik
We discuss the (dual-)gauge transformations and BRST cohomology for the two (1 + 1)-dimensional (2D) free Abelian one-form and four (3 + 1)-dimensional (4D) free Abelian 2-form gau…
Wigner's Little Group as a Generator of Gauge Transformations
Rabin Banerjee
The role of Wigner's little group, as an abelian gauge generator in different contexts, is studied.
The appearence of the resolved singular hypersurface {x_0}{x_1}-{{x_2}^n} =0 in the classical phase space of the Lie group SU(n)
Samir K. Paul, Siddhartha Sen
A classical phase space with a suitable symplectic structure is constructed together with functions which have Poisson brackets algebraically identical to the Lie algebra structure…
Vacuum Expectation Value of the Higgs Field and Dyon Charge Quantisation from Spacetime Dependent Lagrangians
Rajsekhar Bhattacharyya, Debashis Gangopadhyay
The spacetime dependent lagrangian formalism of references [1-2] is used to obtain is used to obtain a classical solution of Yang-Mills theory. This is then used to obtain an estim…
Abelian 2-form gauge theory: special features
R. P. Malik
It is shown that the four -dimensional (4D) free Abelian 2-form gauge theory provides an example of (i) a class of field theoretical models for the Hodge theory, and (ii)…
Cohomological aspects of gauge theories: superfield formalism
R. P. Malik
Some of the key cohomological features of the two -dimensional (2D) free Abelian- and self-interacting non-Abelian gauge theories (having no interaction with matter fields)…
