"Strong 1-boundedness and Property T"
In recent joint work with B. Hayes and D. Jekel, we showed that Property T II_1 factors are strongly 1-bounded in the sense of Jung. In this talk, I will describe the historical context of this problem, and the solution.
This seminar will be held jointly online and in person.

"Blaschke-Santalo inequality for many functions and geodesic barycenters of measures"
Motivated by the geodesic barycenter problem from optimal transportation theory, we prove a natural generalization of the Blaschke-Santalo inequality and the affine isoperimetric inequalities for many sets and many functions.
Based on joint work with A. Kolesnikov.
This seminar will be held jointly online and in person.

"An Introduction to Orbifolds"
It is well-known that the orbit space of a group action on a manifold is generally not a manifold. However, such quotients appear frequently in physics and geometry and possess certain characteristics that make them interesting objects to study. In this talk, we introduce a subclass of these spaces, called orbifolds, and consider different examples coming from both geometry and physics.

"Python and Jupyter for Teaching and Learning"
Jupyter notebook is an open source web application for creating documents which include text, code, data, equations and graphics. We will take a tour of the Jupyter ecosystem including JupyterHub for hosting computational environments, nbgitpuller for sharing notebooks, nbgrader for autograding assignments and Python packages for mathematical computing.

"Generalized superminimal surfaces and holomorphic representation (Part 2)"
I will continue from where we left off last time. We have related conformal minimal immersions of a domain in the complex plane into R^n to harmonic maps, and packaged them in terms of holomorphic data. We have also discussed complex maps and superminimal maps as special cases. This time we will fit these special cases into a hierarchy using complex analysis.

"Shotgun assembly of Erdos-Renyi graphs"
We show that in the regime p>n^{-1/2} polylog(n), the unlabeled G(n,p) random graph can be uniquely reconstructed from its 1-neighborhoods with probability close to one, answering a question of Gaudio and Mossel. Based on joint work with Han Huang.
This seminar will be held jointly online and in person.
