A Spectral Approach to Fixed Points in Product Spaces
Aleksander Ćwiszewski, Wojciech Kryszewski
We study fixed points of mappings on finite products of Banach spaces whose coordinatewise Lipschitz estimates are controlled by a nonnegative matrix . Our main result states th…
Invariance and Strict Invariance for Nonlinear Evolution Problems with Applications
Aleksander Ćwiszewski, Grzegorz Gabor, Wojciech Kryszewski
Sufficient conditions for the invariance of evolution problems governed by perturbations of (possibly nonlinear) -accretive operators are provided. The conditions for the invari…
Constrained Semilinear Elliptic Systems on
Wojciech Kryszewski, Jakub Siemianowski
We prove the existence of solutions in of the following strongly coupled semilinear system of second order elliptic PDEs on \[ \…
Bifurcation from infinity for elliptic problems on
Aleksander Ćwiszewski, Wojciech Kryszewski
In the paper the asymptotic bifurcation of solutions to a parameterized stationary semilinear Schrödinger equation involving a potential of the Kato-Rellich type is studied. It is…
The Bolzano mean-value theorem and partial differential equations
Wojciech Kryszewski, Jakub Siemianowski
We study the existence of solutions to abstract equations of the form , , where A is an abstract differential operator acting in a Banach space ,…
Generalized Nehari manifold and semilinear Schrödinger equation with weak monotonicity condition on the nonlinear term
Francisco Odair de Paiva, Wojciech Kryszewski, Andrzej Szulkin
We study the Schrödinger equations in and in a bounded domain . We assume that is superlinear bu…
