【摘要】 获得了Euler微分方程组-Δui(x)+∑Nj=1Fpij(x,u(x),u(x))+Fξi(x,u(x),u(x))=hi(x),i=1,2,…,m在边界条件ui(x)|Ω=0下存在广义解的一个充分条件.这里ΩRN(N≥3)是具有C1边界的有界开区域,h∈LN2+N2(Ω)m.
【Abstract】 A sufficient condition of existing generalized solutions is obtained to a class of nonlinear Euler differential equation groups:-Δui(x)+∑Nj=1Fpij(x,u(x),u(x))+Fξi(x,u(x),u(x))=hi(x),i=1,2,…,mwith the boundary condition:ui(x)|Ω=0.Where ΩRN(N≥3) is a bounded open domain with boundary C1,h∈L<sup>2NN+2(Ω)m.
