Homological properties of some noncommutative products of Algebras

报告人：吴泉水（复旦大学教授）时间：2021年6月8日10:30-11:30地点：玉泉校区逸夫工商管理楼200-9室摘要：Algebras are supposed to describe spaces as functions. As tensor products of algebras corresponding to the usual products for spaces, some noncommutative constructions of algebras are viewed as the functions of the imaginary noncommutative products of spaces. We try to study the regularity or Gorens...

Examples of non-semisimple Hopf algebra actions on Artin-Schelter regular algebras

报告人：王顶国（曲阜师范大学教授）时间：2021年6月8日9:30-10:30地点：玉泉校区逸夫工商管理楼200-9室摘要：Let k be a base field of characteristic p>0 and let U be the restricted enveloping algebra of a 2-dimensional nonabelian restricted Lie algebra. We classify all inner-faithful U-actions on noetherian Koszul Artin-Schelter regular algebras of global dimension up to three, this is a joint wo...

Full stable trace formula for the group Mp(2n)

报告人：李文威（北京国际数学研究中心）时间：2021年5月14（周五）15:20-16:20地点：玉泉校区邵逸夫科学馆211摘要: The metaplectic covering Mp(2n) of Sp(2n) plays a pivotal role in various aspects of representation theory and arithmetics. In order to harness the full power of Arthur's methods in this setting, we need a stable trace formula for Mp(2n). Thus far, only the elliptic terms have been stab...

Quiver with potentials for generalized cluster algebras from orbifolds

报告人：Dr. Lang Mou（牟浪博士）（University of Leicester, UK）时间： 2021.5.12（周三），16:00-17:00地点：玉泉校区欧阳楼316Abstract: To a marked bordered surface with orbifold points of order 3, we associated a quiver (with loops) with potential. We then connect the cluster structure of the corresponding skew-symmetrizable matrix with the stability conditions and the \tau-tiliting theor...

A universal method for solving elliptic PDEs with singular boundary data on non-smooth domains

Speaker: Prof.Shidong Jiang New Jersey Institute of Technology, USAAbstract: A numerical scheme is presented for the solution of Fredholm second-kind boundary integral equations with right-hand sides that are singular at a finite set of boundary points. The boundaries themselves may be non-smooth. The scheme, which builds on recursively compressed inverse preconditioning (RCIP), ...
