Welcome to the home page of the Mathematics Graduate Student Organization (MGSO) at Texas A&M University in College Station. The purpose of this organization is to encourage communication among students, faculty, and staff, and contribute to a rich social life in the department through cultural and scientific dialogue. We would also like to provide an environment where students in the mathematics department can practice their presentation skills as well as view the techniques of others. It is our goal to be a source of support and information for all graduate students.
The main activity of the MGSO is the Graduate Student Seminar. This seminar is for grad students, (largely) by grad students: Volunteer to give a talk!
Seminar: Fall 2014, Thursdays, Blocker 506A, 4:00-4:50 PM

C. Yan: "Enumerative Combinatorics with Fillings of Polyominoes"
Abstract: An important and active area of Enumerative Combinatorics is the study of combinatorial statistics, which are simply functions from the combinatorial objects to the set of non-negative integers. Many interesting statistics have been investigated over families of combinatorial structures, such as permutations, words, matchings, set partitions, integer sequences, graphs, and multi-graphs. In this talk I will introduce a new combinatorial model, fillings of polyominoes, which provides a unified approach to the classical combinatorial analysis on all the above mentioned structures. I will discuss some recent results and open problems related to this model.
A. Shiu: "What is the Global Attractor Conjecture? "
Abstract: First posed forty years ago, the Global Attractor Conjecture posits that the dynamical systems arising from a certain class of chemical reaction networks are globally stable. In this mini-talk, I will give a history of this conjecture and describe how ideas from algebra and polyhedral geometry have contributed in recent years toward its partial resolution.
