报告题目：Elliptic and parabolic equations with DMO coefficients

时 间：2024年7月15日(星期一)10:00;

地 点：理工楼518

报告摘要：I will present some recent results for elliptic and parabolic equations with Dini mean oscillation (DMO) coefficients. These are extensions of the classical Schauder estimates and the DMO continuity appears to be a minimal condition. For double divergence form equations, we obtained higher regularity near nodel sets.As an application, we established a Hopf type lemma for double divergence form elliptic equations with DMO coefficients and a two-sided estimates for Green’s functions.Most part of my talk is based on joint work with Seick Kim (Yonsei University), Luis Escauriaza (EHU), Jongkeun Choi (Pusan National University), and Boyan Sirakov (PUC-Rio).

欢迎广大师生参加！
