Query: On Struwe-Jeanjean-Toland monotonicity trick   The abstract version of Struwe's monotonicity trick developed by Jeanjean and
Jeanjean-Toland for functionals depending on a real parameter is improved,
under suitable assumptions. Besides, all the machinery is extended to the case
of continuous functionals on Banach spaces, in the framework of non-smooth
critical point theory.
