Another multiplicity result for the periodic solutions of certain systems

Biagio Ricceri

In this paper, we deal with a problem of the type $$\cases{(ϕ(u'))'=\nabla_xF(t,u) & in $[0,T]$\cr & \cr u(0)=u(T)\ , \hskip 3pt u'(0)=u'(T)\ ,\cr}$$ where, in particular, is a…

Applying twice a minimax theorem

Biagio Ricceri

Here is one of the results obtained in this paper: Let be two convex sets each in a real vector space, let be convex and without global minima in $X…
