Friday, February 23, 2018 - 17:00 , Location: Classroom 105 in the D.M. Smith building , Associate Professor , Swarthmore College , Organizer: Joseph Rabinoff
Degeneracy loci of morphisms between vector bundles have been used in a wide range of situations, including classical approaches to the Brill--Noether theory of special divisors on curves. I will describe recent developments in Schubert calculus, including K-theoretic formulas for degeneracy loci and their applications to K-classes of Brill--Noether loci. These recover the formulas of Eisenbud--Harris, Pirola, and Chan--López--Pflueger--Teixidor for Brill--Noether curves. This is joint work with Dave Anderson and Nicola Tarasca.

Friday, January 12, 2018 - 10:10 , Location: Skiles 005 , Rafael de la Llave , School of Mathematics, Georgia Inst. of Technology , Organizer: Rafael de la Llave
This is a preliminary talk for the Workshop "Introduction to Dynamical Systems Methods for Mission Design" that will take place Jan 16-19 in the school of  Mathematics. In this talk, we will present the basics of Hamiltonian dynamics and why it is useful. It ishoped that it will be accesible for people with background in undergraduate differential equations who want to participate in the workshop.

Wednesday, October 11, 2017 - 11:30 , Location: Skiles 005 , Maxie Schmidt , Georgia Tech , mschmidt34@gatech.edu , Organizer: Samantha Petti

Lunch will be provided. The talk will be the first 25 minutes of the hour and then will be followed by discussion. 

In a recent article to appear in the American Mathematical Mothly next year, we use the Lambert series generating function for Euler’s totient function to introduce a new identity for the number of 1’s in the partitions of n. New expansions for Euler’s partition function p(n) are derived in this context. These surprising new results connect the famous classical totient function from multiplicative number theory to the additive theory of partitions. We will define partitions and several variants of Euler's partition function in the talk to state our new results.

CORRECTED DATE.  NOTE:  This is the first in a forthcoming series of colloquia in quantum mathematical physics that will take place this semester.  The series is a spin-off of last year's QMath conference, and is intended to be of broad interest to people wanting to know the state of the art of current topics in mathematical physics.

We shall make an overview of the interplay between the geometry of tubular neighbourhoods of Riemannian manifold and the spectrum of the associated Dirichlet Laplacian.  An emphasis will be put on the existence of curvature-induced eigenvalues in bent tubes and Hardy-type inequalities in twisted tubes of non-circular cross-section.  Consequences of the results for physical systems modelled by the Schroedinger or heat equations will be discussed.
