Kwangil Koh Lecture: Amie Wilkinson, Illuminating a Mathematical Landscape
SAS 2203Turn on a light in the middle of a room: Is every spot illuminated? If the room is a complicated labyrinth, then probably not, but what if the walls of…
Alexander Kiselev, Duke University, Small scale formation in ideal fluids
SAS 4201The incompressible Euler equation of fluid mechanics describes motion of ideal fluid, and was derived in 1755. In two dimensions, global regularity of solutions is known, and double exponential in…
Alex Chandler, NC State, Spectral Sequences Working Seminar
Spectral sequences in Khovanov homology.
Sherli Koshy-Chenthittayil, University of Connecticut, Mathematical modeling in biological scenarios
My research has been in two broad areas namely mathematical biology and disability studies. This talk will touch upon three of my projects in mathematical biology and one project in…
Jonathan Hanselman, Princeton, The cosmetic surgery conjecture and Heegaard Floer homology
Duke University, Physics 119The cosmetic surgery conjecture states that no two surgeries on a given knot produce the same 3-manifold (up to orientation preserving diffeomorphism). Floer homology has proved to be a powerful…

Jeaman Ahn, Kongju National University, Multivariate Hermite Interpolation via Explicit Groebner Basis
Multivariate Hermite interpolation problem asks to find a "small" polynomial that has given values of several partial derivatives at given points. It has numerous applications in science and engineering. Thus, naturally, it…
Atman Vachhani, Mathematics IT, Today’s safe computing practices
This Wednesday, April 10th, from 11AM-12PM in SAS Hall room 4201, Atman Vachhani from Mathematics IT will be leading an interactive seminar on today's safe computing practices. You'll have the opportunity…
Chris Scaduto, Simons Center for Geometry & Physics, Instantons and lattices of smooth 4-manifolds with boundary
Given a 3-manifold Y, what are the possible definite intersection forms of smooth 4-manifolds with boundary Y? Donaldson's theorem says that if Y is the 3-sphere, then all such intersection…
Wen Shen, Penn State University, Scalar Conservation Laws with Discontinuous and Regulated Flux
SAS 4201Conservation laws with discontinuous flux functions arise in various models. In this talk we consider solutions to a class of conservation laws with discontinuous flux, where the flux function is…
Anila Yadavalli, NC State, A curvy way to send messages
SAS 2102Need a more private way of sending notes to your friends during class? Elliptic Curve Cryptography is a method of sending secure messages using tools from algebra and geometry. In…

SAS 4104Sergey Fomin, University of Michigan, Morsifications and Mutations
SAS 1102I will discuss a new and somewhat mysterious connection between singularity theory and cluster algebras, more specifically between the topology of isolated singularities of plane curves and the mutation equivalence…
Juan Villarreal, Virginia Commonwealth University, Logarithmic singularities in vertex algebras
In this talk we want to consider a different kind of singularities in logarithmic vertex algebras. In vertex algebras many properties arise from the locality of their fields. In particular, this implies the…
Pierre Degond, Imperial College, London, Mathematical models of collective dynamics and self-organization
In this talk, I will review some mathematical challenges posed by the modeling of collective dynamics and self-organization. Then, I will focus on two specific problems, first, the derivation of fluid equations…
Jacek Brodzki, Centre for Geometry, Topology, and Applications, Southampton, Persistence in action: quantifying the topology of lungs
Cox 306Topology is dedicated to the study of shapes, and its starting point is an easy-sounding question: How can I tell if two objects are similar? While humans are very adept…
Aida Maraj, University of Kentucky, Quantitative Properties of Ideals arising from Hierarchical Models
SAS 4201We will discuss hierarchical models and certain toric ideals as a way of studying these objects in algebraic statistics. Some algebraic properties of these ideals will be described and a…
