"Strongly Peaking Representations and Compressions of Operator Systems"

We are seeking unitary invariants for d-tuples of operators and more generally for operator systems. However an operator system generally has many completely isometric representations on Hilbert space. So a strong minimality condition is required, and not all operator systems have such a representation.

"Why You Should Care about Discriminants"

You've all made the acquaintance of the humble discriminant b^2 - 4ac of a binary quadratic form because of its appearance under the square root in the quadratic formula. And if you've studied algebraic number theory, you know that algebraic number fields have discriminants too. But did you know that discriminants have connections to the study of vision and black hole thermodynamics?

"Fourier Transforms in Algebraic Geometry"

The Fourier transform is a powerful tool in real analysis and differential equations for understanding families of functions. In this talk, we will discuss how the philosophy of the Fourier transform can be applied in algebraic geometry to relate families of vector bundles on varieties which are so-called “Fourier-Mukai pairs”. As an example, we will look at the Fourier-Mukai pairing between an abelian variety and its Picard group.

"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.
