T-periodic dynamics in a 3D delayed quasispecies model

Journal of Biological Dynamics
We study periodic dynamics and error-threshold behavior in a delayed quasispecies model consisting of a master sequence [Formula: see text] and two mutant populations [Formula: see text].

Topological degree methods for a nonlinear elliptic system with variable exponents

In this paper, we consider the existence of a distributional solution for nonlinear elliptic system governed by (p(x),q(x))-Laplacian operators. We show that the system has at least one solution by using the topological degree theory. Our results improve

Existence of periodic solutions to fractional p(z)-Laplacian parabolic problems

We consider a class of nonlinear parabolic initial boundary value problems having the fractional p(z)-Laplacian operator. By combining variable exponent fractional Sobolev spaces with topological degree theory, we establish theexistence of a time ...

A p(x)-Kirchhoff Type Problem Involving the p(x)-Laplacian-Like Operators With Dirichlet Boundary Condition

This paper deals with a class of p(x)-Kirchhoff type problems involving the p(x)-Laplacian-like operators, arising from the capillarity phenomena, depending on two real parameters with Dirichlet boundary conditions. Using a topological degree for a class

MASS TRANSPORT THROUGH CHARGED MEMBRANES Dieter Bothe and Jan Pruss

, 2001
A modern technique for desalination or softening of water is the so-called nano ltration by means of membranes which carry a xed electric charge. For the mathematical modeling of such processes, two features are particularly important.
