Following Jiaquan Liu,Yuxia Guo and Yajing Zhang,we show that for a > 0,there exists a positive radial solution of the polyharmonic system with u(0) = a for thesupercritical case:(-△)mu = vp,u > 0(-△)mv = uq,v > 0 在Rn中,where m 1 is a positive integer,n > 2m,p +1 1+q +1 1 n-n 2m.
在这篇文章里,我们证明了对任意的a>0,下面多重调和方程组在超临界的情形下存在球对称解满足u(0)=a:(-△)mu=vp,u>0(-△)mv=uq,v>0在Rn中,其中m 1为正整数,n>2m,p+1 1+q+1 1 n-n 2m。
