Abstract
We solve the Neumann problem in the half space for higher order elliptic differential equations with variable self-adjoint t-independent coefficients, and with boundary data in the negative smoothness space where Our arguments are inspired by an argument of Shen and build on known well posedness results in the case p = 2. We use the same techniques to establish nontangential and square function estimates on layer potentials with inputs in Lp or for a similar range of p, based on known bounds for p near 2; in this case we may relax the requirement of self-adjointess.

摘要
我们在半空间解决诺依曼问题 对于具有可变自伴随t独立系数和负平滑空间中的边界数据的高阶椭圆微分方程 在哪里 我们的论点受到 Shen 论点的启发,并建立在p = 2的情况下已知的适定性结果上。我们使用相同的技术来建立非切线和平方函数估计,其中输入为L p或对于类似的p范围,基于p接近 2 的已知界限;在这种情况下,我们可以放宽自伴随的要求。
