Some Convergence Results for RAS-Imp and RAS-PML for the Non-Trapping Helmholtz Problems题目：Some Convergence Results for RAS-Imp and RAS-PML for the Non-Trapping Helmholtz Problems报告人：龚世华 助理教授（香港中文大学（深圳））地点：致远楼101室时间：2024年9月27日 18:30-19:30摘要：We consider two variants of restricted overlapping Schwarz methods for the non-trapping Helmholtz problems, which allow the optic-rays leaving a bounded domain in a uniform time. The first method, know...2024年09月26日

Determine the Number of Clusters by Data Augmentation题目：Determine the Number of Clusters by Data Augmentation报告人：骆威 研究员 （浙江大学）地点：致远楼108室时间：2024年9月26日 14:00-15:00Abstract：Determining the number of clusters is crucial for the successful application of clustering. In this paper, we propose a new order-determination method called the data augmentation estimator (DAE), for the general model-based clustering. The estimat...2024年09月19日

Finite Element Complexes题目：Finite Element Complexes报告人：陈龙 教授 （加州大学尔湾分校）地点：致远楼108室时间：2024年9月13日 下午 16：00-17：00摘要：A Hilbert complex consists of a sequence of Hilbert spaces interconnected by a series of closed, densely defined linear operators, such that the composition of two consecutive maps equals zero. The de Rham complex serves as the most prominent example. Finite element c...2024年09月05日

Q-(R,S)-Stirling Numbers and Q-Multiple Zeta Values at Roots of Unity题目：Q-(R,S)-Stirling Numbers and Q-Multiple Zeta Values at Roots of Unity报告人：小松尚夫 教授 （长崎大学）地点：致远楼101室时间：2024年9月12日 星期四 14:00—1500摘要: We introduce the q-(r,s) Stirling number, which is a q-generalization of the classically famous Stirling number, and shows its properties. As an application, we consider a certain q-multiple zeta function and give the explicit ...2024年09月04日

Beliaev Damping Through Friedrichs Model题目：Beliaev Damping Through Friedrichs Model报告人：李奔 副教授 （浙江万里学院）地点：致远楼101室时间：2024年9月4日 10:00-11:00摘要: We consider the Bose gas at zero temperature. According to Bogoliubov theory the low energy behaviour of the system is described by non-interacting bosonic quasiparticles called phonons. In this presentation we show how the mechanism of Beliaev damping - the dec...2024年09月02日

Rankin-Selberg $L$-Functions on the Edge of the Critical Strip题目：Rankin-Selberg $L$-Functions on the Edge of the Critical Strip报告人：张樵 教授 （得克萨斯克里斯汀大学)地点：致远楼101室时间：2024年8月7日 16:00-17:00摘要：The value distributions of $L$-functions on the edge of the critical strip are important in number theory. In this talk, we will focus on Rankin-Selberg $L$-functions, in particular their lower bounds along the line $\Re s = 1$, and di...2024年08月07日

Canonical Bases for Quantum gl_{m|n} and their Modified Version题目：Canonical Bases for Quantum gl_{m|n} and their Modified Version报告人：Professor Jie Du （University of New South Wales）地点：致远楼108室时间：2024年8月3日 星期六 10:00-11:00摘要：Using quantum differential operators, we construct a quantum gl_{m|n} supermodule structure on a certain polynomial superalgebra. We then extend this representation to its formal power series algebra which cont...2024年07月25日
