Casimir energy for the scalar field: a global approach with cut-off exponential function
M. S. R. Miltão, Franz A. Farias
A global approach with cut-off exponential functions previously proposed is used to obtain the Casimir energy of a massless scalar field in the presence of a spherical shell. The p…

The Hamiltonian BRST quantization of a noncommutative nonabelian gauge theory and its Seiberg-Witten map
Ricardo Amorim, Franz A. Farias
We consider the Hamiltonian BRST quantization of a noncommutative non abelian gauge theory. The Seiberg-Witten map of all phase-space variables, including multipliers, ghosts and t…

Hamiltonian formulation of nonAbelian noncommutative gauge theories
Ricardo Amorim, Franz A. Farias
We implement the Hamiltonian treatment of a nonAbelian noncommutative gauge theory, considering with some detail the algebraic structure of the noncommutative symmetry group. The f…
