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).
