## Classification and evolution of bifurcation curves for a Dirichlet-Neumann boundary value problem and its application.(English)Zbl 1416.37047

The authors study the following boundary value problem: $\begin{gathered} u^{\prime\prime}\left( x\right) +\lambda f\left( u\right) =0,\qquad 0< x <1,\\ u\left( 0\right) =0,\ u^{\prime}\left( 1\right) =-c<0, \end{gathered}$ where $$\lambda>0$$ is a bifurcation parameter and $$c>0$$ is an evolution parameter. They study the classification and evolution of bifurcation curves of positive solutions for the problem, under some suitable assumptions on the nonlinearity of $$f\left( u\right)$$.
