Math Seminars

The Grand Rapids Community College Mathematics Department is pleased to announce that it will host its next Mathematics Seminar on Wednesday, April 5, 3:00-4:00 PM in 103 Cook.  Our speaker will be former GRCC mathematics student Duy Duong-Tran.  His topic is Community Structure in Networks.  The title and abstract may be found below. 

Community structures have been studied by sociologists since the 1930s.  Mathematicians got involved in the 1950s, and tremendous growth in the use of social media has made this a popular area of mathematical study.  Parts of this talk may require knowledge of non-elementary mathematics, but, as always, everyone is invited to attend.         

Pop and cookies will be served at 2:45 PM. 


Community Structure in Networks

The past two decades have witnessed tremendous growth in complex network analysis, as social and biological interactions, and the world-wide web, can be modeled in this framework. In this talk, we will survey different methodological approaches used to analyze community (cluster) structure in complex networks. We will also look at classical bi-section (two-cluster) network models and apply algebraic Eigen decomposition to analyze such networks.
