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.
