Abstract

In this paper, we study the existence of positive solutions for the following nonlinear m-point boundary value problem for an increasing homeomorphism and homomorphism with sign changing nonlinearity: \[ \begin{cases} (\phi(u'))'+a(t) f(t,u(t))=0,\,\,\,\,\, 0<t<1,\\ u'(0)=\Sigma^{m-2}_{i=1}a_i u'(\xi_i), \,\,u(1)=\Sigma^{k}_{i=1}b_i u(\xi_i)- \Sigma^{s}_{i=k+1}b_i u(\xi_i)-\Sigma^{m-2}_{i=s+1}b_i u'(\xi_i), \end{cases} \] where \(\phi: R \rightarrow R\) is an increasing homeomorphism and homomorphism and \(\phi(0) = 0\). The nonlinear term f may change sign. As an application, an example to demonstrate our results has given. The conclusions in this paper essentially extend and improve the known results.
