AMS Movie Night “Hidden Figures”
SAS 1102AMS will be hosting a special showing of Hidden Figures and provide pizza and other snacks.
Vladimir Baranovsky, UC Irvine, “Factorization homology and graph homology”
SAS 4201We 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

Spring 2017 NC State Mathematics Graduation Ceremony
SAS 2203The Math Graduation Ceremony for Spring 2017 will be held on Friday, May 12th at 3:00 pm in 2203 SAS Hall.
Ben Cox, College of Charleston, “On the universal central extension of certain Krichever-Novikov algebras”
SAS 4201We 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.…
Rekha Biswal, Université Laval, “Demazure flags, Chebyshev polynomials and mock theta functions”
SAS 4201The g-stable Demazure modules are a lot of interest because of their connections to representation theory of quantum affine algebras. These modules are indexed by a pair (ell, lambda) where ell is a positive integer and lambda is a dominant integral weight of g and are denoted as D(ell,lambda). Naoi proves that for m>=ell, D(ell,lambda)…
Tom Britton, Stockholm University, “Statistical challenges when analysing emerging epidemic outbreaks”
Cox 306New infectious disease outbreaks have great impact on communities over the world, as recently manifested by the Ebola outbreak. An important statistical task is then to predict the future scenario with and with out preventive measures. In the current talk we will investigate such analyses and see how it can be improved. The main catch…

SAS 4201Advised by Bojko Bakalov.
Khalid Ali Alanezy, “Optimal control of moving interface and phase field separation models”
SAS 4201Advised by Kazufumi Ito.
Renee Brady, “Mathematical modeling of the acute inflammatory response and cardiovascular dynamics in young men”
SAS 4201Advised by Mette Olufsen.
NC State Mathematics Fall Departmental Meeting
SAS 1102At 3:45 we will have ice cream in SAS 4104.
Daniel Scofield, NC State, Patterns in Khovanov homology
SAS 4201Khovanov homology is a recent link invariant that lifts the Jones polynomial. We analyze torsion in Khovanov homology by describing a related homology theory that lifts the chromatic polynomial. In particular, we describe torsion in Khovanov homology of several link families and compute the fourth extreme coefficients of the Jones polynomial for certain links.

SAS 4201AWM Welcome Event
The Association for Women in Mathematics (AWM) will be hosting a welcome event to kick off the beginning of the semester! We will talk a little bit about what our club is about and the types of events we will be hosting throughout the semester, and also play some ice breaker games so everyone can…
Kayla Coleman, An Initialization Algorithm for Gradient-Free Active Subspace Construction
SAS 4201For models with high-dimensional input spaces, constructing accurate response surfaces can be prohibitively expensive. Additionally, the high-dimensionality of the parameter spaces can impact the computational cost of a parameter investigation. Using an active subspace construction, we can efficiently approximate complex models by constructing low-order response surfaces based on a smaller subspace of the high-dimensional parameter…
