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: Fall 2020, Wednesdays, Blocker 628, 4:00-4:50 PM (VIA ZOOM- SEE EMAIL FOR INVITE LINK!)

Title:   Cohen-Macaulay Criterion of modules over an affine semigroup ring

Time / Date:   4:00 - 5:00 , October 14


ohen-Macaulay criterion of an affine semigroup ring is known. However, it is still unclear when the quotient of affine semigroup ring by monomial ideal is Cohen-Macaulay. In this talk, we introduce an algorithm to figure out when the quotient ring is Cohen-Macaulay or not. This algorithm allows us to use Grothendieck's theorem on local cohomology by calculating its graded part using combinatorial construction; standard pairs. We will see how such computation works with a toy example.
