摘要
运用锥理论和不动点指数方法,在与相应的线性算子第一特征值有关的条件下,获得了一个典型弹性梁方程正解的存在性,改进了相关文献的结论.
By cone theory and in the fixed point index method, the existence of positive solutions of a typical elastic beam equation has been obtained under the condition of the first eigenvalue of the corresponding linear operator, and the conclusions of relevant literatures been improved.
