摘要翻译：
本文研究了亚式期权定价中退化抛物型偏微分方程初边值问题的可解性，并研究了这类方程解的微分性质和某些定性性质。利用有限差分格式得到的解，证明了边界退化模型的广义可解性。进一步研究了此类解的规律性。

英文摘要：
This work is focused on the solvability of initial-boundary value problems for degenerate parabolic partial differential equations that arise in the pricing of Asian options, and on the investigation of differential and certain qualitative properties of solutions of such equations. The generalized solvability for such models with degeneracy at the boundaries is proven by employing solutions obtained from finite difference numerical schemes. Furthermore, the regularity of such solutions is studied.
