Positive periodic solutions of neutral logistic equations with distributed delays. <i>Electronic Journal of Differential Equations, 2007</i>(13), pp. 1-10.1072-6691https://hdl.handle.net/10877/14163Using 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)[α(t) - ∑ni=1 αi(t) ∫0-Ti x(t+θ) dμi(θ) = ∑mj=1bj(t) ∫0-T̂j x′(t+θ) dvj(θ)], where the coefficients α, αi, bj are continuous and periodic functions, with the same period. The values Ti, T̂j are positive, and the functions μi, vj are non-decreasing with ∫0-Ti dμi = 1 and ∫0-T̂i dvj = 1.Text10 pages1 file (.pdf)enAttribution 4.0 InternationalPositive periodic solutionNeutral delay logistic equationStrict-set-contractionArticle
