| Abstract: | The existence of positive solutions for a class of second-order three-point boundary value problem was ob-tained by applying the fixed point index theory under some conditions concerning the eigenvalues of relevant linear operator. When compared with other conditions in superlinear and sublinear problems , this conditions are almost the best. so results in this paper extend and improve the main results in early references. |
