加权Bergman空间的若干逼近定理
《同济大学学报(自然科学版)》2014年第12期1924-1927,共4页吴菊杰 陈伯勇

设H2(Ω,φ)为区域Ω上相对于权φ的Bergman空间.给出若Ω为有限个Carathéodory区域之交且φ在Ω-次调和,那么Ω-上的全纯函数在H2(Ω,φ)中稠密,证明了当Ω=Cn且φ是近似圆形时,多项式在H2(Ω,φ)中稠密.

复环面情形的Suita猜想
《数学年刊(A辑)》2014年第1期101-108,共8页董欣 
国家自然科学基金(No.11031008,No.11171255);名古屋大学2012年学生项目的资助
对任意复环面的情形证明了推广的Suita猜想,即απK≥c^2(α∈R),其中c是修正后的对数容度,K是对角线上的Bergman核.还阐明了对任意亏格≥2的紧Riemann面情形的公开问题.文中结果的证明部分地依赖于椭圆函数理论.
