Analysis of a diffusive host-pathogen model with standard incidence and distinct dispersal rates

Advances in Nonlinear Analysis, 2020
This paper concerns with detailed analysis of a reaction-diffusion host-pathogen model with space-dependent parameters in a bounded domain. By considering the fact the mobility of host individuals playing a crucial role in disease transmission, we ...

Front blocking in the presence of gradient drift [PDF]

arXiv, 2018
In this paper we derive quantitative conditions under which a compactly supported drift term blocks the propagation of a traveling wave in a straight cylinder in dimension $n \geq 3$ under the condition that the drift has a potential.

Global asymptotics toward the rarefaction wave for solutions of viscous p -system with boundary effect

, 2000
The initial-boundary value problem on the half-line R+ = (0, oo) for a system of barotropic viscous flow vt — ux = 0, ut + p(v)x = n{y^)x is investigated, where the pressure p(v) = v~y (7 > 1) for the specific volume v > 0.

Long-time asymptotic behavior for the Hermitian symmetric space derivative nonlinear Schrödinger equation

Advanced Nonlinear Studies
Resorting to the spectral analysis of the 4 × 4 matrix spectral problem, we construct a 4 × 4 matrix Riemann–Hilbert problem to solve the initial value problem for the Hermitian symmetric space derivative nonlinear Schrödinger equation.

Polynomial stability of the wave equation with distributed delay term on the dynamical control

Nonautonomous Dynamical Systems, 2021
Using the frequency domain approach, we prove the rational stability for a wave equation with distributed delay on the dynamical control, after establishing the strong stability and the lack of uniform stability.

A memory-type thermoelastic laminated beam with structural damping and microtemperature effects: Well-posedness and general decay

Demonstratio Mathematica
In previous work, Fayssal considered a thermoelastic laminated beam with structural damping, where the heat conduction is given by the classical Fourier’s law and acting on both the rotation angle and the transverse displacements established an ...
