Analytical and numerical analysis of a rotational invariant D=2 harmonic oscillator in the light of different noncommutative phase-space configurations
Everton M. C. Abreu, Mateus V. Marcial, Albert C. R. Mendes +1
In this work we have investigated some properties of classical phase-space with symplectic structures consistent, at the classical level, with two noncommutative (NC) algebras: the…
Noncommutative cosmological models coupled to a perfect fluid and a cosmological constant
E. M. C. Abreu, M. V. Marcial, A. C. R. Mendes +2
In this work we carry out a noncommutative analysis of several Friedmann-Robert-Walker models, coupled to different types of perfect fluids and in the presence of a cosmological co…
Lagrangian formulation for noncommutative nonlinear systems
E. M. C. Abreu, J. Ananias Neto, A. C. R. Mendes +3
In this work we use the well known formalism developed by Faddeev and Jackiw to introduce noncommutativity within two nonlinear systems, the SU(2) Skyrme and O(3) nonlinear sigma m…
