Nonlinear boundary value problems and orlicz spaces [PDF]

open access: yesAnnali di Matematica Pura ed Applicata, 1977
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.

A boundary value problem for a non-linear difference equation [PDF]

open access: yesArchives of Control Sciences
A boundary value problem for a non-linear difference equation of order three is considered. We show that this equation can be interpreted as the equation satisfied by the value function in a stochastic optimal control problem.

On the solutions of nonlinear initial‐boundary value problems [PDF]

open access: yesAbstract and Applied Analysis, 2004
We deal with the general initial‐boundary value problem for a second‐order nonlinear nonstationary evolution equation. The associated operator equation is studied by the Fredholm and Nemitskii operatortheory. Under local Hölder conditions for the nonlinear member, we observe quantitative and qualitative properties of the set of solutions of the given ...

Multiple Positive Solutions of Nonlinear Boundary Value Problem for Finite Fractional Difference

open access: yesAbstract and Applied Analysis, 2014
We consider a discrete fractional nonlinear boundary value problem in which nonlinear term f is involved with the fractional order difference. And we transform the fractional boundary value problem into boundary value problem of integer order difference
