Oct 26th  Jo Nelson’s research group  Symplectic Embeddings on the Virtual BeECH  A symplectic manifold is an even dimensional manifold, which admits a nondegenerate closed 2form, an object akin to dxdy or rdrdθ from multivariable calculus. This object allows one to make 2dimensional measurements (oriented area) within the manifold. A major question in the field is when one symplectic manifold can be symplectically embedded into another, leading to efforts in constructing and obstructing symplectic embeddings. This is particularly interesting and challenging because of the mixture of rigidity (structure) and flexibility (lack of structure) in symplectic geometry. Our research focuses on obstructions to symplectic embeddings of fourdimensional polydisks into fourdimensional ellipsoids. In this talk, we will give an overview of symplectic manifolds, symplectic embedding problems, and obstruction tools like symplectic capacities and the “Beyond ECH” methods. We will then provide a sketch of proof of our new result from the past summer using the former method.

Today's Student Experience in K12 Math Classrooms  I will discuss the challenges and opportunities faced by K12 math educators in 2020. There are many strategies, protocols, and products that are divined on paper as ideal pedagogical solutions, but then must come alive in a messy reality. Find out about the key components that make for great math teaching & learning, and discover and experience how practitioners both individual teachers & at those at various levels of the industry are creating today's student experience in light of (e.g.) the Common Core, the emergence of new digital tools, and the abundance of educational data

EnergyMinimizing Unit Vector Fields in Three Space  Given a smooth real valued function g on the unit sphere S in R3, the function u on the closed unit ball B which coincides with g on S and has least energy∫𝐷𝑢2𝑑𝑥𝐵 is a harmonic function. These show up in classical mathematics, physics,and many applications; e.g. u represents the longtime steadystate temperature distribution resulting from keeping the surface temperature equal to g. Later, many other interesting problems required changing realvalued functions to unit vector fields. This seemingly small change led to many new problems and results. We will look at some of the basic examples, questions and solutions including:

The Many Facets of Harmonic Functions  In this talk, we shall describe harmonic functions on a domain in Rnfrom many different aspects the mean value properties, the PDEs (partial differential equations), the Newtonianpotential, and the probabilistic perspectives. The regularity theory of harmonic functions will be surveyed. Finally, we will discuss some recent constructions of ''weird'' spaces (manifolds) on which the regularity theory blatantly fails, in stark contrast to the Euclidean case. [Our talk is complimentary to Prof. Bob Hardt's talk at the beginning of the semester.]

Anderson localization for disordered quantum graphs  Disorder is one of the central topics in modern science. In this talk, we will discuss a mathematical treatment of a particular disordered system modeling localization of waves in random media. The model in equation was introduced by P. W. Anderson in his Nobel prize winning work in physics which led to a rich mathematical theory of random Schrodinger operators. The present talk is devoted to a particular Anderson model arising in the study of quantum graphs. I will provide an elementary introduction to quantum graphs and mathematical theory of Anderson localization, which lies at the interface of dynamical systems, differential equations, and linear algebra. No previous knowledge of or familiarity with this subject will be assumed
