Christian Scharrer, University of Bonn, Isoperimetric constrained Willmore tori
ZoomIn order to explain the bi-concave shape of red blood cells, Helfrich proposed to study the minimisation of a bending energy amongst closed surfaces with given fixed area and volume.…

MATLAB Tutorial, SIAM Student Chapter part 1
LMP 218The first SIAM event of the semester will be a MATLAB tutorial! This will be a two-part series, starting from the basics of MATLAB coding and building further into more…
Intro to LaTeX Workshop
ZoomHello fellow graduate students! Are you completely new to LaTeX, and need to learn before your first homework? Are you already familiar and looking to practice some basic skills? Are…
Algebra and Combinatorics meet & greet
SAS 4201For this week, we have a special Algebra and Combinatorics meet & greet where we'll get to chat informally and discuss some ideas for the seminar and the upcoming talks. Join Zoom Meeting…
Graduate Numerical Analysis Seminar, Khalil Hall-Hooper, Anomaly Detection with Isolation Forests: Using tree-based methods in machine learning to find outliers in data
ZoomDetermining anomalies in data using classical machine learning techniques typically requires characterizing the notion of what is "normal" or "expected" in the instance space. Upon doing so, one would then…
Andrew Manion, NC State, Heegaard Floer homology and higher tensor products
SAS 4201I will give a brief introduction to Heegaard Floer homology and survey what's known about its "extended" structure via Lipshitz-Ozsvath-Thurston's bordered Floer homology and Douglas-Lipshitz-Manolescu's cornered Floer homology. Then I will sketch…
MATLAB Tutorial, SIAM Student Chapter part 2
LMP 218The first SIAM event of the semester will be a MATLAB tutorial! This will be a two-part series, starting from the basics of MATLAB coding and building further into more…
Laura Colmenarejo, NC State, The Story of My Research
SAS 4201In this talk, I will share with you what kind of problems I work on and what's my motivation. We will talk about the representation theory of finite groups and…
Kate Pearce, NC State, Methodological Considerations for Identifiability and Parameter Subset Selection
ZoomThe issue of parameter identifiability is a pervasive one in determining model parameters from data, specifically in trying to answer whether unique parameter estimation is possible for a given problem.…
Christopher Leonard, NC State, Mapping from Low Fidelity to High Fidelity Analysis for Failure Quantities of Interest
ZoomOften in large numerical simulations decisions are made to reduce the fidelity of particular features in order to simulate the event duration. One common method is the application of shell…
Bessa Pacelli, Universidade Federale de Ceara, Fortaleza, Stochastic half-space theorems for minimal surfaces and H-surfaces of $\mathbb{R}^{3}$.
ZoomIn the 1980s Xavier proved that a complete non-planar minimal surface with bounded curvature of $\mathbb{R}^{3}$ can not lie in half-space. In 1990, Hoffman-Meeks proved that this half-space property holds…
Melisa Zhang, UGA, Constructions toward topological applications of U(1) x U(1) equivariant Khovanov homology
ZoomIn 2018, Khovanov and Robert introduced a version of Khovanov homology over a larger ground ring, termed U(1)xU(1)-equivariant Khovanov homology. This theory was also studied extensively by Taketo Sano. Ross…
Differential Equations and Nonlinear Analysis Seminar: Giulia Cavagnari, Politecnico di Milano, Italy, Evolution equations in Wasserstein spaces driven by dissipative probability vector fields: a variational approach
ZoomIn this talk we present well posedness of Measure Differential Equations, i.e. evolution equations in the Wasserstein space of probability measures driven by dissipative probability vector fields. We take inspiration…
Graduate Student Panel, What is a Prelim?
ZoomAre you a graduate student that has to do a "Preliminary Oral Exam" at some point in the future? Do you also have no idea what a "Preliminary Oral Exam"…
Corey Jones, NC State, Fusion categories in mathematics and physics
SAS 4201Fusion categories are algebraic structures that generalize the representation categories of finite groups. I will explain how fusion categories have become involved in diverse areas of mathematics and physics, from…
