Hopf bifurcation and Turing instability in a diffusive predator-prey model with hunting cooperation

open access: yesOpen Mathematics, 2022
In this article, we study Hopf bifurcation and Turing instability of a diffusive predator-prey model with hunting cooperation. For the local model, we analyze the stability of the equilibrium and derive conditions for determining the direction of Hopf ...

Existence and Nonlinear Stability of Stationary Solutions to the Viscous Two-Phase Flow Model in a Half Line

open access: yesCommunications in Mathematical Research, 2020
The outflow problem for the viscous two-phase flow model in a half line is investigated in the present paper. The existence and uniqueness of the stationary solution is shown for both supersonic state and sonic state at spatial far field, and the ...

Hyers-Ulam stability of a nonautonomous semilinear equation with fractional diffusion

open access: yesDemonstratio Mathematica, 2020
In this paper, we study the Hyers-Ulam stability of a nonautonomous semilinear reaction-diffusion equation. More precisely, we consider a nonautonomous parabolic equation with a diffusion given by the fractional Laplacian. We see that such a stability is

Stability of combination of rarefaction waves with viscous contact wave for compressible Navier-Stokes equations with temperature-dependent transport coefficients and large data

open access: yesAdvances in Nonlinear Analysis, 2022
In this article, we study the large-time behavior of combination of the rarefaction waves with viscous contact wave for a one-dimensional compressible Navier-Stokes system whose transport coefficients depend on the temperature.

Logistic damping effect in chemotaxis models with density-suppressed motility

open access: yesAdvances in Nonlinear Analysis, 2022
This paper is concerned with a parabolic-elliptic chemotaxis model with density-suppressed motility and general logistic source in an n-dimensional smooth bounded domain with Neumann boundary conditions.

A Beale-Kato-Madja breakdown criterion for an Oldroyd-B fluid in the creeping flow regime [PDF]

open access: yes, 2007
We derive a criterion for the breakdown of solutions to the Oldroyd-B model in R3 in the limit of zero Reynolds number (creeping flow). If the initial stress field is in the Sobolev space Hm(R3), m > 5/2, then either a unique solution exists within this ...

TIME-VARYING LYAPUNOV FUNCTIONS AND LYAPUNOV STABILITY OF NONAUTONOMOUS FRACTIONAL ORDER SYSTEMS

open access: yesInternational Journal of Apllied Mathematics, 2019
We present a new inequality which involves the Caputo fractional derivative of the product of two continuously differentiable functions, and establish its various properties. The inequality and its properties enable us to construct potential time-varying
