An existence theorem for singular boundary value problems with sign changing nonlinearities
In this paper we study the existence result of the singular boundary value problem − 1 p (pu) = f (t, u, pu), 0 < t < 1, lim t→0 + p(t)u (t) = 0 = u(1), Under the assumptions that the nonlinearity f may change sign and is singular at u = 0 and t = 1, we present sufficient conditions in Theorem 1.1 to ensure the existence of positive solutions. Our proof is based on the method of approximation a...
متن کاملPOSITIVE SOLUTIONS FOR SINGULAR THREE-POINT BOUNDARY-VALUE PROBLEMS WITH SIGN CHANGING NONLINEARITIES DEPENDING ON x′
Using a fixed point theorem in cones, this paper shows the existence of positive solutions for the singular three-point boundary-value problem x′′(t) + a(t)f(t, x(t), x′(t)) = 0, 0 < t < 1, x′(0) = 0, x(1) = αx(η), where 0 < α < 1, 0 < η < 1, and f may change sign and may be singular at x = 0 and x′ = 0.

متن کاملA Positive Solution for Singular Discrete Boundary Value Problems with Sign-changing Nonlinearities
Let a,b (b > a) be nonnegative integers. We define the discrete interval [a,b] = {a,a + 1, . . . ,b}. All other intervals will carry its standard meaning, for example, [0,∞) denotes the set of nonnegative real numbers. The symbol Δ denotes the forward difference operator with step size 1, that is, Δu(k) = u(k + 1)− u(k). Furthermore for a positive m, Δm is defined as Δmu(k)= Δm−1(Δu(k)). In thi...
متن کاملAn Approximation Approach to Eigenvalue Intervals for Singular Boundary Value Problems with Sign Changing and Superlinear Nonlinearities
Recommended by Ivan T. Kiguradze This paper studies the eigenvalue interval for the singular boundary value problem −u gt, u λht, u, t ∈ 0, 1, u0 0 u1, where g h may be singular at u 0, t 0, 1, and may change sign and be superlinear at u ∞. The approach is based on an approximation method together with the theory of upper and lower solutions. Copyright q 2009 Haishen L ¨ u et al. This is an ope...
