متن کاملDelay-induced periodic phenomenon in a diffusive regulated logistic model
The diffusive logistic growth model with time delay and feedback control is considered. First, the well-posedness and permanence of solutions are discussed by using some comparison techniques. Then, the sufficient conditions for stability of nonnegative constant steady states are established, and the occurrence of Hopf bifurcation at positive steady state is performed. Next, the bifurcation pro...
متن کاملExistence of positive periodic solutions for a periodic logistic equation
In this paper, we study a more generalized class of periodic logistic equations. By using the method of coincidence degree, a set of sufficient conditions is obtained for the existence of positive periodic solutions of the equations which are under the consideration. 2002 Elsevier Science Inc.

متن کاملPeriodic solutions of logistic type population model with harvesting
We consider a bifurcation problem arising from population biology du(t) dt = f(u(t))− εh(t), where f(u) is a logistic type growth rate function, ε ≥ 0, h(t) is a continuous function of period T such that ∫ T 0 h(t)dt > 0. We prove that there exists an ε0 > 0 such that the equation has exactly two T -periodic solutions when 0 < ε < ε0, exactly one T -periodic solution when ε = ε0, and no T -peri...
متن کاملinvestigating 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...
