Further Results and Unexplored Problems

  • Guglielmo Feltrin
Part of the Frontiers in Mathematics book series (FM)


In this final chapter, we collect some recent results that take into consideration classes of indefinite problems which we have not discussed in the present manuscript. Moreover, we illustrate some interesting uninvestigated issues that would be the subject of future researches. Our purpose is to describe a panorama of topics related to the discussion in the first two parts of the manuscript and, in this spirit, we prefer to avoid proofs and other technicalities.
