Complex Network Analysis using Mathematica
Tuesday, 10/14/2014, 3:10pm - 11:59pm
Speaker: Chenghang Du, GW
Abstract: This is a hands-on workshop aimed at undergraduate students and other interested audience. I will walk you through some examples of using Mathematica for complex network analysis. I will also outline a few potential projects, including collaboration network, Boolean dynamics, social network, and time series analysis. Students are welcomed to bring laptop to the workshop.
Minimal length elements: some interaction between

Speaker: Xuhua He (University of Maryland)
Title: Minimal length elements: some interaction between combinatorics, representation theory, and arithmetic geometry
Abstract: The study of minimal length elements in a conjugacy class of a Weyl group arises in the study of representation theory. Minimal length elements have many remarkable combinatorial properties.

Is the Solar system stable? — a historical topic revisited
Friday, 9/26/2014, 5:00pm - 11:59pm
This event is co-sponsored by the GW Confucius Institute
Abstract: The system I am going to talk about is an idealized model: to study n mass points which move in 3 dimensional space according to Newton’s law. We assume further that n-1 of these fictions mass points havevery small masses compared to the remaining one, which plays the role of the sun. I shall introduce some ideas to study this problem and give a brief review on new progress in the field.
