Predation-induced dispersal toward fitness for predator invasion in predator–prey models

open access: yesJournal of Biological Dynamics, 2023
In this paper, we consider a predator–prey model with nonuniform predator dispersal, called predation-induced dispersal (PID), which represents predator motility depending on the maximal predation rate and the predator death rate in a spatially ...

Existence and uniqueness of positive solutions for Kirchhoff type beam equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
This paper is concerned with the existence and uniqueness of positive solutions for the fourth order Kirchhoff type problem \begin{equation*} \begin{cases} u''''(x)-\Big(a+b\int_0^1(u'(x))^2dx\Big)u''(x)=\lambda f(u(x)),& x\in(0,1),\\ u(0)=u(1)=u''(0)=u''

Qualitative properties and global bifurcation of solutions for a singular boundary value problem

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
This paper deals with a singular, nonlinear Sturm–Liouville problem of the form $\{A(x)u'(x)\}'+\lambda u(x)=f(x,u(x),u'(x))$ on $(0,1)$ where $A$ is positive on $(0,1]$ but decays quadratically to zero as $x$ approaches zero. This is the lowest level of

Global Bifurcation Structure of a Predator-Prey System with a Spatial Degeneracy and B-D Functional Response

open access: yesComplexity, 2021
In this paper, we investigate a predator-prey system with Beddington–DeAngelis (B-D) functional response in a spatially degenerate heterogeneous environment.

Global bifurcation of coexistence states for a prey-predator model with prey-taxis/predator-taxis

open access: yesAdvanced Nonlinear Studies, 2023
This article is concerned with the stationary problem for a prey-predator model with prey-taxis/predator-taxis under homogeneous Dirichlet boundary conditions, where the interaction is governed by a Beddington-DeAngelis functional response.

Global Dynamics of the Vibrating System of a Tristable Piezoelectric Energy Harvester

open access: yesMathematics, 2022
Global dynamics of a piezoelectric energy harvester with tristable potential is investigated. The dynamical model of a cantilever beam energy harvester is considered; its static bifurcation is also discussed.

Pattern formation of a Schnakenberg-type plant root hair initiation model

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
This paper concentrates on the diversity of patterns in a quite general Schnakenberg-type model. We discuss existence and nonexistence of nonconstant positive steady state solutions as well as their bounds.

Precise Asymptotics for Bifurcation Curve of Nonlinear Ordinary Differential Equation

open access: yesMathematics, 2020
We study the following nonlinear eigenvalue problem −u″(t)=λf(u(t)),u(t)>0,t∈I:=(−1,1),u(±1)=0, where f(u)=log(1+u) and λ>0 is a parameter. Then λ is a continuous function of α>0, where α is the maximum norm α=∥uλ∥∞ of the solution uλ associated with λ ...
