本文考虑RN中的多调和系统(-Δ)mu=vα,(-Δ)mv=uβ,其中N> 2 m,α ≠ 1,β ≠ 1,其中(-Δ)是多调和算子.对于1/(α+1)+1/(β+1)>(N− 2 m)/N,我们证明了非负径向光滑解的不存在性.对于1<α,β<(N+2 m)/(N− 2 m),我们证明了非负光滑解的不存在性.另外,对于(N− 2 m)β<Nα+2m或(N− 2 m)α<Nβ+2m且α,β>1,我们证明了多重调和不等式组(−Δ)mu <$vα,(−Δ)mv <$uβ的非负光滑解的不存在性.更一般地,我们可以证明上述所有结果对于RN中的系统(−Δ)mu=vα,(−Δ)μ =uβ成立,其中N>max{2 m,2n}且α <$1,β <$1。
In this note, we consider the polyharmonic system (−Δ)mu=vα, (−Δ)mv=uβin RNwith N>2m and α⩾1, β⩾1, where (−Δ)mis the polyharmonic operator. For 1/(α+1)+1/(β+1)>(N−2m)/N, we prove the non-existence of non-negative, radial, smooth solutions. For 1<α,β<(N+2m)/(N−2m), we show the non-existence of non-negative smooth solutions. In addition, for either (N−2m)β<Nα+2m or (N−2m)α<Nβ+2m with α,β>1, we show the non-existence of non-negative smooth solutions for polyharmonic system of inequalities (−Δ)mu⩾vα, (−Δ)mv⩾uβ. More general, we can prove that all the above results hold for the system (−Δ)mu=vα,(−Δ)nv=uβin RNwith N>max{2m,2n} and α⩾1, β⩾1.
