The minimal wave speed of the Lotka-Volterra competition model with seasonal succession
Discrete and Continuous Dynamical Systems - B, 2021 This paper focuses on the minimal wave speed of time-periodic traveling waves to a Lotka-Volterra competition model with seasonal succession. It is the first time the general conditions of linear selection and nonlinear selection have been derived by the

Slow and fast minimal speed traveling waves of the FKPP equation with chemotaxis [PDF]
Journal de Mathématiques Pures et Appliquées, 2021 We examine a general model for the Fisher-KPP (FKPP) equation with nonlocal advection. The main interpretation of this model is as describing a diffusing and logistically growing population that is also influenced by intraspecific attraction or repulsion.

Fisher-KPP waves and the minimal speed on hexagonal lattice
Journal of Differential EquationsThe hexagonal structure is ubiquitous in nature. The propagation phenomena occurring in a media with a hexagonal structure remain to be explored. One way of exploring this question is to formulate lattice dynamical systems and analyze the propagation ...

Electronic Journal of Qualitative Theory of Differential Equations, 2018 In this paper we prove a new estimate of the threshold wave speed for traveling wavefronts of the reaction–diffusion–convection equations of the type \[v_\tau + h(v) v_x= \left[ D(v)v_x \right]_x + f(v) \] where \(h\) is a convective term, \(D\) is a ...

Minimal-speed selection of traveling waves to the Lotka–Volterra competition model
Journal of Differential Equations, 2019 In this paper the minimal-speed determinacy of traveling wave fronts of a two-species competition model of diffusive Lotka–Volterra type is investigated. First, a cooperative system is obtained from the classical Lotka–Volterra competition model.

Minimal wave speed on a diffusive SIR model with nonlocal delays
Electronic Journal of Differential Equations, 2018 This article concerns the minimal wave speed of a diffusive SIR model with nonlocal delays, in which the dynamics of disease has no positive outbreak threshold. By constructing a pair of super and sub-solutions, we establish the existence of traveling

Minimal wave speed of a nonlocal diffusive epidemic model with temporal delay
Rocky Mountain Journal of Mathematics, 2014 This paper is concerned with the traveling wave solutions of an epidemic model with nonlocal dispersal and time delay. By a characteristic equation, a threshold is defined. If the wave speed is larger than the threshold, the existence of traveling wave solutions is proved by combining upper-lower solutions with monotone iteration.

Determination of wave speed and distensibility of flexible tubes using diameter and velocity [PDF]
, 2009 It is well accepted that wave speed is one of the key factors describing wave propagation in arteries. Local wave speed is directly related to the mechanical properties of the arterial wall and is widely used to determine the arterial distensibility ...
