摘要
讨论如下的半线性方程：－△ｕ＝ｇ（｜ｘ｜）ｆ（ｕ）ｉｎΩｕ＝０ｏｎΩ｛这里Ω＝｛ｘ∈ＲＮ：Ｒ＜｜ｘ｜＜Ｒ｝Ｎ≥２，０＜Ｒ＜Ｒ＜＋∞．在适当的条件下。
In this paper , we discuss the following semilinear equation-△u=g(|x|)f(u) in Ω u=0 on Ωwhere Ω={x∈R N : R<|x|<} N≥2, 0<R<<+∞. Under some assuptions , by meams of varitional method we obtain that there are two distinct positive radial solutions.
