Variational approach for a class of cooperative systems
  The aim of this work is to ascertain the characterization of the existence of coexistence states for a class of cooperative systems supported by the study of an associated non--local equation through classical variational methods. Thanks to those results we are able to obtain the blow--up behaviour of the solutions in the whole domain for certain values of the main continuation parameter.
