Analysis Seminar

Artur Płaneta, Agricultural University of Krakow

"Conjugations in L2 spaces on the unit circle and the real line"

One of the axioms of standard quantum theory requires that the Hamiltonian H, which is the operator that expresses the dynamics of the quantum system, be Hermitian. However, this requirement is mathematical rather than physical in character. One possibility to replace this requirement is to consider the conjugation PT and PT symmetries.

Pure Math Grad Student Colloquium

Joaco Prandi, Department of Pure Mathematics, University of Waterloo

"Julia Sets"

In this talk, we will introduce the concept of Julia sets and some of the basic properties and their connections to the Mandelbrot set. We will introduce the concept of self-similarity and quasi-self-similarity, and we will give some interesting results. The talk will be closed with some of the open questions related to the study of Julia sets.

This seminar will be held jointly online and in person:

Algebraic Geometry Working Seminar

Ruxandra Moraru, Department of Pure Mathematics, University of Waterloo

"Higgs Bundles"

Last week, Robert introduced the notion of Higgs bundle over Riemann surfaces. In this talk, I will provide some background on Higgs bundles and explain how they are related to the Yang-Mills equations and the cotangent bundle of the moduli space of stable bundles. I will also discuss how Higgs bundles can be generalized to higher-dimensional complex manifolds.
