Nonlinear nonhomogeneous Robin problems with almost critical and partially concave reaction
N. S. Papageorgiou, D. D. Repovš, C. Vetro
We consider a nonlinear Robin problem driven by a nonhomogeneous differential operator, with reaction which exhibits the competition of two Carathéodory terms. One is parametric, $…
Iterative reconstruction of signals on graph
Emanuele Brugnoli, Elena Toscano, Calogero Vetro
We propose an iterative algorithm to interpolate graph signals from only a partial set of samples. Our method is derived from the well known Papoulis-Gerchberg algorithm by conside…
Nonlinear multivalued Duffing systems
Nikolaos S. Papageorgiou, Calogero Vetro, Francesca Vetro
We consider a multivalued nonlinear Duffing system driven by a nonlinear nonhomogeneous differential operator. We prove existence theorems for both the convex and nonconvex problem…
