Asymptotic Behavior of Solutions of a Periodic Reaction-Diffusion System of a Competitor-Competitor-Mutualist Model

Limit cycles for competitor–competitor–mutualist Lotka–Volterra systems

It is known that a limit cycle (or periodic coexistence) can occur in a competitor–competitor–mutualist Lotka–Volterra system  ẋ1 = x1(r1 − a11x1 − a12x2 + a13x3), ẋ2 = x2(r2 − a21x1 − a22x2 + a23x3), ẋ3 = x3(r3 + a31x1 + a32x2 − a33x3), where ri , ai j are positive real constants [X.

Asymptotic Behavior of a Periodic Diffusion System

A Reaction-Diffusion System of a Predator-Prey-Mutualist Model

Mutualism is part of many significant processes in nature. Mutualistic benefits arising from modification of predator-prey interactions involve interactions of at least three species. In this paper we investigate the homogeneous Neumann problem and Dirichlet problem for a reaction-diffusion system of three species--a predator, a mutualist-prey, and a mutualist. The existence, uniqueness, and bo...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
