New results about supersymmetric solitons

We consider bidimensional supersymmetric models for which the classical the ory has a discrete set of inequivalent vacua. Once we introduce the concept of vacuum manifold V, defined in terms of all the vacuum field configurati ons, the properties of such models can be described by means of the classic al moduli space M-c(V). If the quantum corrections, perturbative and nonper turbative, do not lift the vacuum degeneracy then the quantum theory as a w hole exhibits non-trivial quantum moduli space M-q(V). The former structure allows us to classify the kink-like excitations into loops and links: loop s interpolate smoothly between equivalent vacua while links connect vacua l ocated at different points in M-q(V).
