受学校人事处和国际合作与交流基金资助，应理学院数学系的邀请，十大老品牌网赌信誉平台排名数学学科首席学术顾问美国俄亥俄州立大学的Friedman院士和俄亥俄州立大学生物数学中心的副主任Yuan Lou教授将于9月1日—9月14日来十大老品牌网赌信誉平台排名访问讲学并进行学术交流，现将讲学时间、地点、内容通知如下，欢迎相关专业老师和同学参加。
Sep 02 Monday
9:00-10:00 Avner Friedman
Title: A radially symmetric tumor with one type of cell of constant density: global existence, stationary solutions, stability of stationary solutions
10:00-12:00 Yuan Lou
Title: Some Mathematical Models from Spatial Ecology I: Evolution of slow dispersal
地点：正心楼111
Sep 03 Tuesday
9:00-10:00 Avner Friedman
Title: Same model: Stability of radial solution for GENERAL initial perturbations; symmetry breaking bifurcations of the radial solution
10:00-12:00 Yuan Lou
Title: Some Mathematical Models from Spatial Ecology II: Diffusion induced extinction
地点：正心楼116
Sep 04 Wednesday
9:00-10:00 Avner Friedman
Title: A tumor model with several type of cells (proliferating, quiescence, dead) in a general domain: local existence; radial solutions
10:00-12:00 Yuan Lou
Title: Some Mathematical Models from Spatial Ecology III: Directed movement vs. random movement
地点：正心楼103
Sep 05 Thursday
9:00-10:00 Avner Friedman
Title: A wound healing model with free boundary: local existence
10:00-12:00 Yuan Lou

地点：正心楼105
Sep 06 Friday
9:00-10:00 Avner Friedman
Title: Introducing a new model of avascular tumor, with several types of cell, as a new research project. The aim is to prove that small tumors will disappear and large tumor will grow; the radially symmetric case is already a nice open problem.
10:00-12:00 Yuan Lou
Title: TBA
地点：正心楼205
The second week: Start discussing the projects that will be introduced in the last lectures
时间、地点：与第一周相同
