On the Existence of Positive Periodic Solutions for Second-Order Functional Differential Equations with Multiple Delays
and Applied Analysis 3 The techniques used in this paper are completely different from those in 5 . Our results are more general than those in 5 in two aspects. Firstly, we relax the conditions of the coefficient a t appeared in an equation in 5 and expand the range of its values. Secondly, by constructing a special cone and applying the fixed-point index theory in cones, we obtain the essentia...
متن کاملExistence of positive solutions for a boundary value problem of a nonlinear fractional differential equation
This paper presents conditions for the existence and multiplicity of positive solutions for a boundary value problem of a nonlinear fractional differential equation. We show that it has at least one or two positive solutions. The main tool is Krasnosel'skii fixed point theorem on cone and fixed point index theory.
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 کاملExistence of Time Periodic Solutions for One-Dimensional Newtonian Filtration Equation with Multiple Delays
In this paper, we study one-dimensional Newtonian filtration equation including unbounded sources with multiple delays. The existence of nonnegative non-trivial time periodic solutions will be established by the Leray-Schauder fixed point theorem based on some suitable Lyapunov functionals and some a priori estimates for all possible periodic solutions.
متن کاملPositive solutions for a scalar differential equation with several delays
For a scalar delay differential equation ẋ(t) + ∑m k=1 ak(t)x(hk(t)) = 0, hk(t) ≤ t, we obtain new explicit conditions for the existence of a positive solution. c © 2007 Elsevier Ltd. All rights reserved.
