Existence of Positive Solutions for Singular Eigenvalue Problems

چکیده
In this paper, we discuss the existence, nonexistence, and multiplicity of positive solutions for a class of singular eigenvalue problems. Some of our theorems are new, while others extend earlier results obtained by Zhang and Kong [12]. The interesting point is that the authors obtain the relation between the existence of solutions and the parameter λ. The arguments are based on the fixed point index theory and the upper and lower solutions method.

متن کاملBranches of positive and free boundary solutions for some singular quasilinear elliptic problems
We study the existence and multiplicity of solutions, strictly positive or nonnegative having a free boundary (the boundary of the set where the solution vanishes) of some one-dimensional quasilinear problems of eigenvalue type with possibly singular nonlinear terms. © 2008 Elsevier Inc.

متن کاملPositive Solutions of Singular Third-Order Three-Point Boundary Value Problems
where η ∈ (12 , 1) is a constant, g may be singular at t = 0 and/or 1. Moreover, F (t, u) may also have singularity at u = 0. The existence theorems of positive solutions for singular third-order third-point boundary value problems are obtained by using the first eigenvalue of the corresponding linear problems. Our results significantly extend and improve many known results including singular a...
متن کاملEigenvalue problems for a class of singular quasilinear elliptic equations in weighted spaces
Abstract: In this paper, by using the Galerkin method and the generalized Brouwer’s theorem, some problems of the higher eigenvalues are studied for a class of singular quasiliner elliptic equations in the weighted Sobolev spaces. The existence of weak solutions is obtained for this problem.
متن کاملThe Relationship between the Infinite Eigenvalue Assignment for Singular Systems and the Solvability of Polynomial Matrix Equations
Two related problems, namely the problem of the infinite eigenvalue assignment and that of the solvability of polynomial matrix equations are considered. Necessary and sufficient conditions for the existence of solutions to both the problems are established. The relationships between the problems are discussed and some applications from the field of the perfect observer design for singular line...
