About us
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: Spring 2012, Thursdays, Milner 216, 4:00-4:50 PM

Speaker: Prof. Frank Sottile
Title: Galois groups of Schubert problems
Time / Date: 4:00 - 5:00 , January 26
Abstract
The Galois group of a field extension encodes all of its symmetries and it is the basic invariant of the field extension. Enumerative geometric problems, which are fundamental in algebraic geometry, also have Galois groups which encode the symmetries and the intrinsic structure of the geometric problem.
These are, however, difficult to determine and hard to study. For a wide class of well-structured geometric problems (the Schubert Calculus) there are many approaches and even some results. My talk will introduce these geometric Galois groups and discuss some of the approaches to studying them and some of the results that we have obtained. Thi is ongoing work with collaborators at other institutions and students at TAMU, including Abraham Martin del Campo and Chris Brooks.
