Three solutions to a class of neumann doubly eigenvalue elliptic systems driven by a (p1,...,pn)-laplacian
(The Korean Mathematical Society, 2010-11-30)
In this paper we establish the existence of at least three weak solutions for Neumann doubly eigenvalue elliptic systems driven by a (P-1, ... , p(n))-Laplacian. Our main tool is a recent three critical points theorem of ...
Degenerate anisotropic differential operators and applications
(Springer Nature, 2011-01-01)
The boundary value problems for degenerate anisotropic differential operator equations with variable coefficients are studied. Several conditions for the separability and Fredholmness in Banach-valued L-p spaces are given. ...
Browder-krasnoselskii-type fixed point theorems in banach spaces
(Springer Nature, 2010-01-01)
We present some fixed point theorems for the sum A + B of a weakly-strongly continuous map and a nonexpansive map on a Banach space X. Our results cover several earlier works by Edmunds, Reinermann, Singh, and others.
Existence results for first and second order semilinear impulsive differential inclusions
(Uniwersytet Mikolaja Kopernika/Nicolaus Copernicus University, 2005-09-01)
In this paper we prove existence results for first and second order semilinear impulsive differential inclusions in Banach spaces.
Twin positive periodic solutions of second order singular differential systems
(Uniwersytet Mikolaja Kopernika/Nicolaus Copernicus University, 2005-06-01)
In this paper, we study positive periodic solutions to singular second order differential systems. It is proved that such a problem has at least two positive periodic solutions. The proof relies on a nonlinear alternative ...
