建立了一类边界退化椭圆型线性二阶偏微分方程解的Schauder先验估计和正则性。此外,给出了一个光滑的源函数,证明了直到算子退化的边界部分解的正则性。本文中描述的退化椭圆算子有许多不同的应用,包括在数学金融中随机波动模型中作为仿射扩散过程的生成器,在数学生物学中作为扩散过程的生成器,以及在多孔介质的研究中作为扩散过程的生成器。

英文摘要:
We establish Schauder a priori estimates and regularity for solutions to a class of boundary-degenerate elliptic linear second-order partial differential equations. Furthermore, given a smooth source function, we prove regularity of solutions up to the portion of the boundary where the operator is degenerate. Degenerate-elliptic operators of the kind described in our article appear in a diverse range of applications, including as generators of affine diffusion processes employed in stochastic volatility models in mathematical finance, generators of diffusion processes arising in mathematical biology, and the study of porous media.
