AI总结:

本文证明了密度有界时 sigma-2 方程的连续 2-凸解具有局部 W^{2,1} 正则性,密度连续时具有局部 W^{2,p} 正则性。

AI中文摘要:

我们证明,在密度被正常数上下界所限制的条件下,$\sigma_{2}$ 方程的连续 $2$-凸解在每个维度都属于 $W^{2,1}_{\mathrm{loc}}$。此外,若密度连续,则解属于 $W^{2,p}_{\mathrm{loc}}$ 对所有 $1<p<\infty$ 成立。

英文摘要:

We prove that continuous $2$-convex solutions of the $σ_{2}$ equation with a density bounded above and below by positive constants belong to $W^{2,1}_{\mathrm{loc}}$ in every dimension. If, in addition, the density is continuous, the solutions belong to $W^{2,p}_{\mathrm{loc}}$ for every $1<p<\infty$.
