摘要
研究一类非线性二阶差分方程边值问题解的多重性.当非线性项满足一定条件时,利用变分方法及临界点理论中的三解定理,证明了该问题至少有三个不同的解.
In this paper, multiple solutions for a nonlinear second-order differential boundary value problem are studied. If certain conditions are imposed on the nonlinear term, the result is proved that there are at least three solutions by using the variational method and the three solutions theorem in the critical point theory
