摘要

我们证明,若 Rn\mathbb{R}^{n} 装备某种非加倍度量,且对一族特殊的 Young 函数 Φ\Phi 成立 Orlicz-Sobolev 不等式,则形如 divA(x,u)u=ϕ0divAϕ1\mathrm{div}\mathcal{A}\left( x,u\right) \nabla u=\phi _{0}-\mathrm{div}_{A} \vec{\phi}_{1} 的拟线性无穷退化椭圆散度方程的弱解局部有界。此外,只要存在全局 Orlicz-Sobolev 估计,我们就建立了解的最大值原理。我们通过实施 Moser 迭代方法得到这些结果,这是该技术应用于无穷退化方程的首例。这些结果部分推广了先前已知的此类方程解的估计,但此前右端不含漂移项。我们还得到了非负解的小负次幂的界;这些将在后续论文中用于获得解的连续性。

备注

This file replaces a previous submission in which there was an error in the proof of continuity of solutions. As in the previous files, the current paper showcases the implementation of a Moser iteration infinite degenerate geometries and also includes a drift term on the right-hand side. The proof of continuity of solutions will be achieved in a subsequent work
