报告人： 陈发敏副教授（北京交通大学） 报告摘要： Extended (N≥4) superconformal Chern-Simons-matter (CSM) theories in 3D are natural candidates of the dual gauge theories of multi M2-branes, which are fundamental objects in M-theory. In the literature, the N=4,5,6 CSM theories were constructed by using ordinary Lie 2-algebras, and the N=8 theory was constructed by using Nambu 3-algebra. We introduce the notion of symplectic 3-algebra, and construct all N≥4 CSM theories in terms of this unified 3-algebraic structure. Using superalgebras to realize the 3-algebras, we recover all known examples of the N≥4 CMS theories, and derive some new N=4 quiver gauge theories as well. 报告人简介：陈发敏，2010年毕业于犹他大学（University of Utah）,获物理学博士学位。2010年-2012年在北京大学物理学院作博士后。2012年入职北京交通大学，工作至今；职称为副教授。研究方向为M理论中的AdS/CFT对偶，侧重于CFT理论的构建与研究。最近致力于构建与M5膜相关的6维N=(1,0)规范理论。 |
