A note on permanence for a nicholson's blowflies model with delay
(2019-01-01)
In this work, we will establish conditions to guarantee the permanence of the solution of the Nicholson's blowies model with delay (Formula Presented) where R; Γ : R -→ [0; ∞) are bounded continuous functions, r = sup t2R ...
Existence of positive T-periodic solutions of a generalized Nicholson’s blowflies model with a nonlinear harvesting term
(Elsevier, 2012-09)
We give sufficient and necessary conditions for the existence of at least one positive T -periodic solution for a generalized Nicholson’s blowflies model with a nonlinear harvesting term. Our results extend those of the ...
Global attractivity and persistence in a discrete population model
(2000)
We study the attractivity properties of equilibrium points of the scalar delay difference equation xn+1-xn= -δxn+pf(xn-k) which arises in many contexts in the ecology. New sufficient conditions for the global stability of ...
Speed Selection and Stability of Wavefronts for Delayed Monostable Reaction-Diffusion Equations
(2016)
We study the asymptotic stability of traveling fronts and the front's velocity selection problem for the time-delayed monostable equation with Lipschitz continuous reaction term . We also assume that g is -smooth in some ...
Periodic solutions of differential equations with a general piecewise constant argument and applications
(UNIV SZEGED, BOLYAI INSTITUTE, 2010)
In this paper we investigate the existence of the periodic solutions
of a quasilinear differential equation with piecewise constant argument
of generalized type. By using some fixed point theorems and some new
analysis ...
