Mathematics and Science of Complex Networks

Thursday, 9/18/2014, 3:10pm - 11:59pm

Speaker: Yongwu Rong (GWU)

Abstract: Complex networks arise naturally in many disciplines, from computer networks to interactions of biological cells, from air traffic design to social networks. Over the past decade, there has been a great deal of new interests in this field, largely due to the explosive amount of data on various networks. An urgent need now is to extract useful information to understand the structure of these networks.

Logic -Topology Seminar

Simplicial modules, quantum plane and q-polynomial of rooted trees

Friday, 9/12/2014, 6:30pm - 11:59pm

Speaker: Przytycki, Jozef (GWU)

Abstract: For the 30th anniversary of the Homflypt polynomial of links, I propose
a new polynomial invariant of rooted trees. I will relate this to the Kauffman bracket (version of the Jones polynomial)
and to (pre)simplicial categories.

Colloquium

Solved and Unsolved Problems From The On-Line Encyclopedia of Integer Sequences

Friday, 5/9/2014, 5:00pm - 11:59pm

Speaker: Neil J. A. Sloane, Mathematics Department, Rutgers University, Piscataway, NJ.

Abstract: The On-Line Encyclopedia of Integer Sequences is a database of number sequences, which in its fiftieth year now contains nearly a quarter of a million entries. This talk will describe some of the highlights, including the toothpick sequence, curling numbers, ``lunar'' arithmetic, and some very unusual recurrences. There will be several unsolved problems, music, and a movie.
