AI总结:

针对带低阶项的二阶线性散度型椭圆方程的弱解,推导了Schauder-Orlicz型估计,识别了低阶数据的最优关联空间,并推广至重排不变Banach函数空间。

摘要:

首先处理Orlicz设定$X=L^\psi$。在Young函数$\psi$和系数的适当假设下,识别了低阶数据的最优关联空间。然后得到了$W^{1,\psi}$中的先验估计。接下来将讨论扩展到重排不变Banach函数空间。引入了一个类$(\mathcal C)$来刻画那些使得相应的关联空间$Y$产生Schauder型估计的空间$X$。最后以Lorentz空间作为具体例子进行了检验。

英文摘要:

Schauder Orlicz-type estimates are derived for weak solutions to second-order linear elliptic equations in divergence form with lower-order terms. The Orlicz setting $X=L^ψ$ is treated first. Under suitable assumptions on the Young function $ψ$ and on the coefficients, the optimal associated space for the lower-order datum is identified. An \textit{a priori} estimate in $W^{1,ψ}$ is then obtained. The discussion is next extended to rearrangement-invariant Banach function spaces. A class $(\mathcal C)$ is introduced to characterize the spaces $X$ for which a corresponding associated space $Y$ yields Schauder-type estimates. Lorentz spaces are finally examined as concrete examples.
