通过建立一个新的Hilbert空间H,在H中讨论一类包含Hardy位势1/x4(N≥5)的双调和方程,利用Hardy-Rellich不等式,证明了双调和方程特非平凡解的存在性.
The problem of biharmonic equations with Hardy potential 1/x4(N≥5) is investigated based on an establishment of a new Hilbert space H.Furthermore,it is showed that the solvability of these problems through a Hardy-Relich inequality.
