Ellie Dannenberg, An Introduction to Circle Packing
A circle packing is the mathematical name for a collection of circles. I am interested in circle packings with a fixed pattern of tangencies between the circles. Given a tangency…

SAS 2102For the schedule and program see https://trianglemtc.wordpress.com/visible-math-at-ncsu-febuary-1-2019-2/ Organized by Arvind Saibaba and Irina Kogan in collaboration with the Triangle Math Teachers' Circle.
Rachel Neville, University of Arizona, Orthogonal Transformations and Symmetry Groups
In this demo, we will discover some interesting properties about symmetry by starting with some special transformation matrices. This talk will be a combination of interactive work with the material…
Stepan Paul, Harvard, Isoptics, or how to design the perfect stadium
How could you design a stadium so that a rectangular playing field looks the same size to every spectator? What about for a circular wrestling ring? In this talk, we…
Guang Lin, Uncertainty Quantification and Scientific Machine Learning for Complex Engineering and Physical Systems
SAS 1102Experience suggests that uncertainties often play an important role in quantifying the performance of complex systems. Therefore, uncertainty needs to be treated as a core element in the modeling, simulation,…
Andrew Papanicolaou, NYU, Principal component analysis for implied volatility surfaces
Principal component analysis (PCA) is a useful tool when trying to uncover factor models from historical asset returns. For the implied volatilities of U.S. equities there is a PCA-based model…
Valentine’s Day Cookie Contest by the MGSA
MGSA is holding its annual cookie contest! If you would like to be entered into the contest, we ask that you bring at least 2 dozen of your best cookies…
Dmitriy Morozov, Persistent Homology: Applications and Computation
Room 3211, Engineering Building II, Centennial Campus Raleigh, NCPersistent homology is a key method in topological data analysis, a young but rapidly growing field at the intersection of computational geometry and algebraic topology. Persistence is used to describe…
Paata Ivanisvili, UC Irvine, Bellman function in analysis
Many estimates in analysis have certain “common structures” which makes it possible to obtain them with what is now called Bellman function method. Originally the method appeared in control theory…
