Existence of positive periodic solutions for neutral functional differential equations
We find sufficient conditions for the existence of positive periodic solutions of two kinds of neutral differential equations. Using Krasnoselskii's fixed-point theorem in cones, we obtain results that extend and improve previous results.

In this article, we show the existence of three positive symmetric solutions for the integral boundary-value problem with $\phi$-Laplacian $$\displaylines{ (\phi(u'(t)))'+f(t,u(t),u'(t))=0,\quad t\in[0,1],\cr u(0)=u(1)=\int_0^1u(r)g(r)\,dr ...

Existence of solutions for a coupled quasilinear system on time scales
In this work we study a quasilinear system of equations on time scales. Using the Krasnoselskii fixed-point theorem, sufficient conditions are given for the existence of positive solutions.

Positive solutions for the beam equation under certain boundary conditions
We consider a boundary-value problem for the beam equation, in which the boundary conditions mean that the beam is embedded at one end and fastened with a sliding clamp at the other end.
