"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.

"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:
