Periodic Solutions and Positive Solutions of First and Second Order Logistic Type ODEs with Harvesting
It was recently shown that the nonlinear logistic type ODE with periodic harvesting has a bifurcation on the periodic solutions with respect to the parameter : u′ = f(u)− h(t). Namely, there exists an 0 such that for 0 < < 0 there are two periodic solutions, for = 0 there is one periodic solution, and for > 0 there are no periodic solutions, provided that ∫ T 0 h(t)dt > 0. In this paper we look...

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 کاملPositive Periodic Solutions of Neutral Logistic Equations with Distributed Delays
Using a fixed point theorem of strict-set-contraction, we establish criteria for the existence of positive periodic solutions for the periodic neutral logistic equation, with distributed delays, x′(t) = x(t) h a(t)− n X i=1 ai(t) Z 0 −Ti x(t+θ) dμi(θ)− m X j=1 bj(t) Z 0 −T̂j x′(t+θ) dνj(θ) i , where the coefficients a, ai, bj are continuous and periodic functions, with the same period. The value...
متن کاملSingular solutions of perturbed logistic-type equations
We are concerned with the qualitative analysis of positive singular solutions with blow-up boundary for a class of logistic-type equations with slow diffusion and variable potential. We establish the exact blow-up rate of solutions near the boundary in terms of Karamata regular variation theory. This enables us to deduce the uniqueness of the singular solution. 2011 Elsevier Inc.
