DYNAMICAL CONFINEMENT IN BOSONIZED 2-DIMENSIONAL QCD

In the bosonized version of two-dimensional theories nontrivial boundary conditions (topology) play a crucial role. They are inevitable if one wants to describe nonsinglet states. In Abelian bosonization, color is the charge of a topological current in terms of a nonlinear meson field. We show that confinement appears as the dynamical collapse of the topology associated with its nontrivial boundary conditions.
