摘要
推广了两个多重临界点存在定理。作为其应用的例子,主要讨论了二阶半线性椭圆方程边值问题-u=f(x,u),u=0有三个互异解的条件。
Two multiple critical point theorems are generalized. As an example of their applications, the conditions of the Dirichlet problem for the semilinear elliptic equation - △u = f (x, u) in Ω and u = 0 on Ω, which possesses three solutions are discussed.
