  人力资源部教师发展中心开展“学者论坛”系列学术活动,定期邀请与我校教师研究领域相关的知名学者,以专题报告的形式与师生分享和研讨最新研究动态和成果,旨在为教师提供学术探讨和交流的平台,开拓教师学术视野。现将第37期论坛安排如下,欢迎广大师生参加。

  一、主 题:Calculus rules for subdifferentials

  二、主讲人:Vera Roshchina,Research Fellow,RMIT University

  三、时 间:2016年11月9日(周三)16:30

  四、地 点:清水河校区主楼A1-512

  、内容简介

  Subdifferentials generalize the notion of derivative for functions which are nonsmooth. There are different ways to define such generalizations. I will talk about geometric construction of Fréchet and limiting subdifferentials for finite minima of functions subdifferentiable in the sense of Demyanov-Rubinov. Such functions have convex directional derivatives and under additional assumptions their subdifferentials preserve enough directional information to make such construction possible. For instance, approximate convex functions introduced by Huynh Van Ngai, Dinh The Luc and Michel Théra satisfy such assumptions.

  六、主讲人简介

  Dr. Vera Roshchina is a DECRA Research Fellow at the School of Science, RMIT University. She works on finite dimensional optimization problems, focusing on the geometry of underlying objects. This includes subdifferential calculus in finite dimensions and the study of facial structure of convex sets.

  Vera received her Ph.D. in applied mathematics from the City University of Hong Kong in 2009. Prior to joining RMIT University in 2015 she held postdoctoral positions at University of Evora (Portugal), Federation University Australia and The University of Melbourne. She has published around 30 papers in international journals in the areas of subdifferential calculus, real complexity and dynamical systems.
