Topological Mass vs. Dynamical Mass: Novelty in (2+1)-dimensional Space-Time
Toyoki Matsuyama, Hideko Nagahiro
The restriction of space-time dimensions to "2+1" leads us to a novel quantum field theory which has the Chern-Simons term in its action. This term changes the nature of gauge inte…

Canonical Structure of the Non-Linear Sigma-Model in a Polynomial Formulation
C. D. Fosco, T. Matsuyama
We study the canonical structure of the non-linear Sigma-model in a polynomial, first-order representation. The fundamental variables in this description are a non-Abelian…

The Polynomial Formulation of the U(1) Non-Linear Sigma-Model in 2 Dimensions
C. D. Fosco, T. Matsuyama
We investigate some properties of a first-order polynomial formulation of the U(1) non-linear sigma-model in two Euclidean dimensions. The variables in this description are a 1-for…
