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…
Period Estimates for Autonomous Evolution Equations with Lipschitz Nonlinearities
Aleksander Ćwiszewski, Władysław Klinikowski
We derive an estimate for the minimal period of autonomous strongly damped hyperbolic problems. Our result corresponds to the works by Yorke, Busenberg et al. for ordinary differen…
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…
Stationary solutions and connecting orbits for -Laplace equation
Aleksander Cwiszewski, Mateusz Maciejewski
We deal with one dimensional -Laplace equation of the form under Dirichlet boundary condition, where and $f…
