Minimal wave speed of traveling wavefronts in delayed Belousov-Zhabotinskii model [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
This paper is concerned with the traveling wavefronts of Belousov-Zhabotinskii model with time delay. By constructing proper upper and lower solutions and applying the theory of asymptotic spreading, the minimal wave speed is obtained under the weaker ...

Traveling wave solutions for an integrodifference equation of higher order

open access: yesAIMS Mathematics, 2022
This article is concerned with the minimal wave speed of traveling wave solutions for an integrodifference equation of higher order. Besides the operator may be nonmonotone, the kernel functions may be not Lebesgue measurable and integrable such that the

Generalized Horndeski-like Einstein Gauss-Bonnet inflation with massless primordial gravitons

open access: yesNuclear Physics B, 2021
In this work we shall introduce a theoretical framework comprised by a non-minimal coupled canonical scalar field, a non-minimal coupling to the Gauss-Bonnet invariant and a non-minimal kinetic coupling.

Minimal wave speed of competitive lattice dynamical systems with delays

open access: yesAdvances in Difference Equations, 2018
This paper deals with the minimal wave speed of delayed lattice dynamical systems. We obtain the minimal wave speed by presenting the existence and nonexistence of traveling wave solutions, which completes the earlier results.

Minimal Wave Speed in an Integrodifference System of Predator-Prey Type

open access: yesDiscrete Dynamics in Nature and Society, 2020
This article studies the minimal wave speed of traveling wave solutions in an integrodifference predator-prey system that does not have the comparison principle. By constructing generalized upper and lower solutions and utilizing the theory of asymptotic

Minimal travelling wave speed and explicit solutions in monostable reaction-diffusion equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
We investigate the connection between the existence of an explicit travelling wave solution and the travelling wave with minimal speed in a scalar monostable reaction-diffusion equation.

Minimal wave speed in a dispersal predator–prey system with delays

open access: yesBoundary Value Problems, 2018
This paper is concerned with the minimal wave speed in a nonlocal dispersal predator–prey system with delays. We define a threshold. By presenting the existence and nonexistence of traveling wave solutions, we confirm that the threshold is the minimal ...

Travelling waves in a nonlocal reaction-diffusion equation as a model for a population structured by a space variable and a phenotypical trait [PDF]

open access: yes, 2012
We consider a nonlocal reaction-diffusion equation as a model for a population structured by a space variable and a phenotypical trait. To sustain the possibility of invasion in the case where an underlying principal eigenvalue is negative, we ...
