Nicholas Higham, University of Manchester, “Challenges in multivalued matrix functions”

SAS 1102

Multivalued matrix functions arise in solving various kinds of matrix equations. The matrix logarithm is the prototypical example. Another example is the Lambert W function of a matrix, which is much less well known but has been attracting recent interest. A theme of the talk is the importance of choosing appropriate principal values and making…

Weekly Brown Bag Lunch

SAS 4104

Please join us for our last weekly brown bag lunch of the year! You bring your lunch, and we will bring a delicious treat. Everyone (not just women) is welcome to join or stop by for as long as they can!

Ephraim Bililign, Taylor Garnowski, William Reese and Brandon Summers, NC State Undergraduate Student Honors Presentations

1. Ephraim Bililign Title: Measuring the temperature of granular systems Abstract: Granular systems, or collections of athermal mesoscale particles, are immune to temperature in the conventional sense. Thus, to describe the behavior of an jammed assortment of grains, we turn to a modified thermodynamics built on forces and volumes. I will discuss the experimental measurements…

Nam Le, Indiana University, “The Monge-Ampere eigenvalue problem and global smoothness of the eigenfunctions”

SAS 4201

In this talk, I will first introduce the Monge-Ampere eigenvalue problem on general bounded convex domains and related analysis. Then I will discuss the recent resolution, in joint work with Ovidiu Savin, of global smoothness of the eigenfunctions of the Monge-Ampere operator on smooth, bounded and uniformly convex domains in all dimensions. A key ingredient…

Beverly Setzer, Samuel Weber and Christopher Cardullo, NC State Undergraduate Student Honors Presentations

1. Beverly Setzer Title: Detecting Hidden Nodes in Neuronal Networks using Adaptive Filtering Abstract: The identification of network connectivity from noisy time series is of great interest in the study of network dynamics. This connectivity estimation problem becomes more complicated when we consider the possibility of hidden nodes within the network. These hidden nodes act…

Vladimir Baranovsky, UC Irvine, “Factorization homology and graph homology”

SAS 4201

We give a brief overview of factorization homology theory due to Ayala, Francis and Tanaka and explain how it leads to a (still mostly conjectural) generalization of graph homology to homotopy commutative algebras, and an efficient computation of knot invariants coming from factorization homology (at least for alternating links).

MGSA and AMS Cinco de Mayo Celebration

SAS 4104

MGSA and AMS will be providing free Moes burritos to celebrate Cinco de Mayo and the end of the semester! All math grad students are welcome, but you must RSVP by Wednesday, May 3 at noon if you plan to eat a burrito. For info about how to RSVP, please email mgsa.ncstate@gmail.com. All math grad…

Ben Cox, College of Charleston, “On the universal central extension of certain Krichever-Novikov algebras”

SAS 4201

We will describe results on the center of the universal central extension of certain Krichever-Novikov algebras. In particular we will describe how various families of classical and non-classical orthogonal polynomials appear. We will also provide certain new identities of elliptic integrals. This material we will cover was obtained in joint work with V. Futorny, J.…
