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...骆威 研究员 (浙江大学)致远楼108室2024年9月26日 14:00-15:00

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...陈龙 教授 (加州大学尔湾分校)致远楼108室2024年9月13日 下午 16:00-17:00

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 ...小松尚夫 教授 (长崎大学)致远楼101室2024年9月12日 星期四 14:00—15:00

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...李奔 副教授 (浙江万里学院)致远楼101室2024年9月4日 10:00-11:00

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...张樵 教授 (得克萨斯克里斯汀大学)致远楼101室2024年8月7日 16:00-17:00

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...Professor Jie Du (University of New South Wales )致远楼108室2024年8月3日 星期六 10:00-11:00

Nonlocal Conservation Laws for Traffic Flow Modeling题目:Nonlocal Conservation Laws for Traffic Flow Modeling报告人:黄旷 助理教授 (香港中文大学)地点:致远楼101室时间:2024年7月31日 星期三 14:00-15:00摘要:The emerging connected and automated vehicle technologies allow vehicles to perceive and process information in a wide spatial range, which motivates the modeling of traffic flows with nonlocal inter-vehicle interactions. For example, the l...黄旷 助理教授 (香港中文大学)致远楼101室2024年7月31日 星期三 14:00-15:00
