本文利用一种新的三个泛函不动点定理得到了p-Laplacian方程在具有非线性边值条件时:至少存在三个正解的充分条件,并且举了一个简单例子来说明得到的结论。
By a simple application of a new three functionals fixed point theorem, sufficient conditions axe obtained to guarantee the existence of at least three positive solutions for p-Laplacian equation: (φp(u′))′ + α(t)f(t,u(t)) = 0 subject to nonlinear boundary value conditions. An example is presented to illustrate the theory.
