国际“双微”(微分几何、微分方程)会议,是著名数学家陈省身教授倡议,并由中国科学院和我国教育部组织和领导的。自1980以来,一年一度地在我国召开了“双微”学术讨论会·今年8月29日至9月9日在北京召开的第四届国际“双微”会议(简称DD4),是由中国科学院和教育部委托北京大学主办的。这次会议的主题是讨论微分动力体系与常微分方程研究中的最新问题·参加这次会议的有我国40所大学、研究所的75名代表以及美、英、西德、瑞士、奥地利、加拿大等国的13名代表。国际数学会理事长J·Moser教授也出席了会议。
International “double micro” (differential geometry, differential equations) conference, is a famous mathematician Professor Chen Sungsong initiative, organized and led by the Chinese Academy of Sciences and China’s Ministry of Education. Since 1980, the “Double Wei” Symposium has been held in our country once a year. The Fourth International “Double Wei” Conference (DD4) held in Beijing from August 29 to September 9 this year is held by Chinese Academy of Sciences and the Ministry of Education commissioned by Peking University. The theme of the conference was to discuss the latest issues in the study of differential dynamical systems and ordinary differential equations. The conference included 75 representatives of 40 universities and institutes in China as well as representatives from the United States, Britain, West Germany, Switzerland, Austria, Canada 13 representatives from other countries. Professor J. Moser, President of the International Mathematical Society also attended the conference.
