Usando metodi dell'analisi funzionale si ottengono teoremi di esistenza delle soluzioni di un'equazione della forma Lx+Nx=0 dove L e un operatore differenziale ordinario lineare autoaggiunto di ordine pari, positivo, mentre N e un operatore non necessariamente lineare.
Nonlinear boundary value problems for ordinary differential equations, Equations involving nonlinear operators (general), Spaces of measurable functions (\(L^p\)-spaces, Orlicz spaces, Köthe function spaces, Lorentz spaces, rearrangement invariant spaces, ideal spaces, etc.)
