Minimal wave speed and spread speed of competing pioneer and climax species

Applicable Analysis, 2014
In this article, for a diffusive population model describing interaction of pioneer-climax species, we explore the issues of spreading speed, linear determinacy and traveling wave fronts. Applying the theory developed by Weinberger et al. [J. Math. Biol.

Mechanical Characteristics Regulation of V-Shaped Standing-Wave Ultrasonic Motors With Minimal Quantity Lubrication

Tribology Transactions, 2023
Friction drive and wear control is a tough issue for linear standing-wave ultrasonic motors with intermittent contact and impact friction. For the widely recognized reduction of friction/wear, minimum quantity lubrication was adopted to improve the ...

Minimal-speed selection of traveling fronts to a three components lattice competition system

International Journal of Biomathematics, 2022
In this paper, we study the traveling wave problem for a three species lattice competition system with monostable nonlinearity. We are interested in the linear or nonlinear determinacy of the minimal wave speed.

Existence of travelling waves with their minimal speed for a diffusing Lotka–Volterra system

Nonlinear Analysis: Real World Applications, 2003
Existence of travelling waves for a diffusing Lotka-Volterra system is investigated. There exist travelling waves which propagate from an equilibrium point to another one. The authors have proved the existence of at least a wave front with its minimal speed.

A reducing mechanism on wave speed for chemotaxis systems with degenerate diffusion

Calculus of Variations and Partial Differential Equations, 2020
This paper is concerned with traveling wave solutions for a chemotaxis model with degenerate diffusion of porous medium type. We establish the existence of semi-finite traveling waves, including the sharp type and C1\documentclass[12pt]{minimal ...

Minimal wave speed of a diffusive SIR epidemic model with nonlocal delay

International Journal of Biomathematics, 2019
This paper is concerned with the minimal wave speed in a diffusive epidemic model with nonlocal delays. We define a threshold. By presenting the existence and the nonexistence of traveling wave solutions for all positive wave speed, we confirm that the threshold is the minimal wave speed of traveling wave solutions, which models that the infective ...
