Bai, Chuanzhi Positive solutions for second-order three-point eigenvalue problems. (English) Zbl 1204.34029 Abstr. Appl. Anal. 2010, Article ID 236826, 8 p. (2010). Summary: By means of the fixed point index theorem in cones, we get an existence theorem concerning the existence of a positive solution for the second-order three-point eigenvalue problem\[ x''(t)+\lambda f(t,x(t))=0,\quad 0\leq t\leq 1,\;x(0)=0,\;x(1)=x(\eta), \]where \(\lambda\) is a parameter. An illustrative example is given to demonstrate the effectiveness of the obtained result.
