Comments on Noncommutative Sigma Models
We review the derivation of a noncommutative version of the nonlinear sigma model on CP and it’s soliton solutions for finite θ emphasizing the similarities it bears to the GMS scalar field theory. It is also shown that unlike the scalar theory, some care needs to be taken in defining the topological charge of BPS solitons of the theory due to nonvanishing surface terms in the energy functional...
متن کاملNoncommutative Linear Sigma Models
We examine noncommutative linear sigma models with U (N) global symmetry groups at the one-loop quantum level, and contrast the results with our previous study of the noncommutative O(N) linear sigma models where we have shown that Nambu-Goldstone symmetry realization is inconsistent with continuum renormaliza-tion. Specifically we find no violation of Goldstone's theorem at one-loop for the U ...
متن کاملEquivalence of Projections as Gauge Equivalence on Noncommutative Space
Projections play crucial roles in the ADHM construction on noncommutative R. In this article a framework for the description of equivalence relations between projections is proposed. We treat the equivalence of projections as gauge equivalence on noncommutative space. We find an interesting application of this framework to the study of U(2) instanton on noncommutative R: A zero winding number c...

Here we present arguments in favor of equivalence of noncommutative models in various dimensions.
متن کاملOn Quantum Equivalence of Dual Sigma Models: Sl(3) Examples
The equivalence of several SL(3) sigma models and their special Abelian duals is investigated in the two loop order of perturbation theory. The investigation is based on extracting and comparing various β functions of the original and dual models. The role of the discrete global symmetries is emphasized. 1 1. Introduction Various target space duality transformations [1-3] ('T duality') connecti...
