On Multiple Positive Solutions of Positone and Non-positone Problems
In this paper, we consider the following problem: − u= f (u) in , u= 0 on ∂ , (1.1) where is the ball BR = {x ∈ R ; |x| < R}, | · | is the Euclidean norm in R, and f : R+ → R is a locally Lipschitzian continuous function. We are concerned with two classes of problems, namely, (i) the positone problem: f (0)≥ 0; (ii) the non-positone problem: f (0) < 0. The study of positone problems was initiat...
متن کاملMultiple Positive Solutions for Singular Semi-positone Delay Differential Equation
In this paper, we obtain new existence results for multiple positive solutions of a delay singular differential boundary-value problem. Our main tool is the fixed point index method.

This paper studies semi-positone systems of equations by using phase plane analysis and fixed point theory.
متن کاملPositive Solutions for Classes of Positone/semipositone Systems with Multiparameters
We study the existence and nonexistence of solution for a system involving p,q-Laplacian and nonlinearity with multiple parameteres. We use the method of lower and upper solutions for prove the existence of solutions.
