We establish constructive conditions for the appearance of solutions of a linear Fredholm boundary-value problem for a system
of ordinary differential equations in the critical case and propose an iterative procedure for finding these solutions. The
range of values of a small parameter for which the indicated iterative procedure is convergent is estimated.

This paper is concerned with a nonhomogeneous multipoint boundary-value problem (BVP) of a second-order differential equation with one-dimensional p-Laplacian. Using multiple fixed-point theorems, new sufficient conditions to guarantee the existence of at least three solutions of this BVP are established. An example is presented to illustrate the main results. The first emphasis of this paper is to show that the approach to get three positive solutions of a BVP by using multiple fixed-point theorems can be extended to treat nonhomogeneous BVPs. The second emphasis is put on the nonlinear term f involved with the first-order delta operator. 相似文献

In this paper, using a recent result of Ricceri, we prove two multiplicity theorems for the problem −u″=λf(u)+μg(x,u), u(0)=u(1)=0, extending a previous result that G. Bonanno obtained for μ=0. 相似文献

We prove a theorem on the unique existence of a solution to a nonlinear equation with maxima and demonstrate its continuous
dependence on the initial function and the parameter of the problem. We also establish conditions for the existence of a nonzero
solution to a two-point boundary-value periodic problem in dependence of both linear and nonlinear terms of the equation. 相似文献

We study the problem of finding conditions for the existence of solutions of weakly nonlinear Noetherian boundary-value problems
for systems of ordinary differential equations and the construction of these solutions. A new iterative procedure with accelerated
convergence is proposed for the construction of solutions of a weakly nonlinear Noetherian boundary-value problem for a system
of ordinary differential equations in the critical case.

This paper investigates the existence and multiplicity of positive solutions for a class of nonlinear boundary-value problem of second-order differential equations with integral boundary conditions in ordered Banach spaces. The arguments are based upon a specially constructed cone and the fixed point theory in a cone for strict set contraction operators. The nonexistence of a positive solution is also studied. 相似文献

This paper studies the bifurcation of positive solutions for a three-point boundary-value problem of nonlinear fractional differential equations with parameter. Using the topological degree theory and the bifurcation technique, the existence of positive solutions is investigated and some sufficient conditions are obtained. The study of two illustrative examples shows that the obtained new results are effective. 相似文献
