临界增长非线性椭圆方程Neumann　边值问题的分歧

The Bifurcation of Neumann Boundary Value Problems of Nonlinear Elliptic Equations Involving Critical Sobolev EXponent

考虑如下方程在（０，０）点的分歧：其中为有界域，为单位外法向。给出了（０，０）点是分歧点和不是分歧点的一个充分条件。

The bifurcation of(0 , 0) for the following equations is considered as follows:Where is bounded domain, The auther has proved that (0,0) is not a bifurcation point of the equations on sonie conditions and (0,0) is a bi-furcation point on other proper conditions.
