應(yīng)yl7703永利官網(wǎng)邀請(qǐng),美國(guó)布朗大學(xué)董弘桀教授將于2024年7月14日-21日訪問蘭州大學(xué)并于7月15日上午作學(xué)術(shù)報(bào)告，歡迎全校師生參加.

報(bào)告題目：Elliptic and parabolic equations with DMO coefficients

時(shí) 間：2024年7月15日(星期一)10:00;

地 點(diǎn)：理工樓518

報(bào)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).

歡迎廣大師生參加！
