摘要

对于定义在RN\mathbb{R}^N中有界开子集Ω\Omega上的任意fLN(Ω)f \in L^N(\Omega),我们证明了11-Laplacian 方程div(uu)=f{-}\mathrm{div}{(\frac{\nabla u}{|\nabla u|})} = fΩ\Omega中的解uW01,1(Ω)u \in W_0^{1, 1}(\Omega)在一个正 Lebesgue 测度集上满足u=0\nabla u = 0。如果f∉LN(Ω)f \not\in L^N(\Omega)在弱-LNL^{N}函数的 Marcinkiewicz 空间中具有小范数,或者如果uu是相关能量泛函的 BV 极小化子,则同样的性质也成立。证明依赖于 Stampacchia 截断方法。
