AI中文摘要:
研究发现,Ladyzhenskaya & Ural'tseva在非一致椭圆型问题内部梯度估计中的充分条件同样具有必要性。具体而言,非参数极小曲面表现出与解的局部Lipschitz正则性兼容的最大非一致率,而Finn的经典理论以及Bombieri、De Giorgi与Miranda的理论无法扩展到Bernstein型2之外。
英文摘要:
The sufficient conditions of Ladyzhenskaya \& Ural'tseva \cite{lu70} for interior gradient estimates in nonuniformly elliptic problems are found to be also necessary. Specifically, nonparametric minimal surfaces exhibit the maximal nonuniformity rate compatible with the local Lipschitz regularity of solutions, and the classical theory of Finn \cite{fin54} and Bombieri \& De Giorgi \& Miranda \cite{bdm69} doesn't extend beyond Bernstein genre $2$.
