%X The aim of this monograph is to present a comprehensive survey of results about existence, multiplicity, perturbation from symmetry and concentration phenomena for a class of quasi-linear elliptic equations coming from functionals of the calculus of variations which turn out to be merely continuous. Some tools of non-smooth critical point theory will be employed.
%K Critical points
%K non-smooth functionals
%K weak slope
%K deformation theorem
%K invariant functionals
%K mountain pass theorem
%K relative category.
