Space-Time Diffeomorphisms in Noncommutative Gauge Theories
Marcos Rosenbaum, J. David Vergara, L. Roman Juarez
In previous work [Rosenbaum M. et al., J. Phys. A: Math. Theor. 40 (2007), 10367-10382, hep-th/0611160] we have shown how for canonical parametrized field theories, where space-tim…
Noncommutative Field Theory from Quantum Mechanical Space-Space Noncommutativity
Marcos Rosenbaum, J. David Vergara, L. Roman Juarez
We investigate the incorporation of space noncommutativity into field theory by extending to the spectral continuum the minisuperspace action of the quantum mechanical harmonic osc…
Noncommutative spaces, the quantum of time and the Lorentz symmetry
Juan M. Romero, J. D. Vergara, J. A. Santiago
We introduce three space-times that are discrete in time and compatible with the Lorentz symmetry. We show that these spaces are no commutative, with commutation relations similar…
Gauge systems with noncommutative phase space
Vladimir Cuesta, Merced Montesinos, Jose David Vergara
Some very simple models of gauge systems with noncanonical symplectic structures having as the gauge algebra are given. The models can be interpreted as noncommutative ve…
Bosonic string theory with constraints linear in the momenta
Merced Montesinos, Jose David Vergara
The Hamiltonian analysis of Polyakov action is reviewed putting emphasis in two topics: Dirac observables and gauge conditions. In the case of the closed string it is computed the…
Hamiltonian Solution of the Schwinger Model with Compact U(1)
Román Linares, Luis F. Urrutia, J. David Vergara
The complete exact solution of the Schwinger model with compact gauge group U(1), in the Hamiltonian approach, is presented . The compactification is imposed by demanding that the…
