چکیده

in this work, by employing the krasnosel'skii fixed point theorem, we study the existence of positive solutions of a three-point boundary value problem for the following fourth-order differential equation begin{eqnarray*} left { begin{array}{ll} u^{(4)}(t) -f(t,u(t),u^{prime prime }(t))=0 hspace{1cm} 0 leq t leq 1, &amp; u(0) = u(1)=0, hspace{1cm} alpha u^{prime prime }(0) - beta u^{prime prime prime }(0)=0, hspace{1cm} u^{prime prime }(1)- alpha u^{prime prime }(eta)=0, &amp; end{array} right. end{eqnarray*} where $beta > 0, 0< eta 0$.

Research Article Existence of Positive Solutions for Fourth-Order Three-Point Boundary Value Problems

As is pointed out in [1, 2], boundary value problems for secondand higher-order differential equations play a very important role in both theory and applications. Recently, an increasing interest in studying the existence of solutions and positive solutions to boundary value problems for fourth-order differential equations is observed; see, for example, [3–8]. In this paper, we are concerned wi...

Positive solutions of nonlinear fourth order boundary value problems with local and nonlocal boundary conditions

We establish new existence results for multiple positive solutions of fourth order nonlinear equations which model deflections of an elastic beam. We consider the widely studied boundary conditions corresponding to clamped and hinged ends and many nonlocal boundary conditions, with a unified approach. Our method is to show that each boundary value problem can be written as the same type of pert...

Using the five functional fixed point theorem due...
