“Relative Randomness and van Lambalgen’s Theorem - Part 2”

We continue last week’s presentation and present a proof of van Lambalgen’s Theorem. To conclude this subsection, we also remark on some of the consequences of this result. Time per- mitting, we also discuss some applications of relativized randomness to lowness and highness.

"Dynamical Analogue of Results by Bombieri-Masser-Zannier and Habegger"

First, we briefly explain how results and questions in diophantine geometry give rise to interesting problems in arithmetic dynamics. Then we focus on dynamical analogue of the following results by

Bombieri, Masser, Zannier and Habegger.

“Applications of order isomorphisms of C*-algebras”

We will review known results about order isomorphisms of C*-algebras, and will describe some applications to complete positivity of maps and a generalization of the Choi matrix. (This is joint work with Vern Paulsen.) Then we will describe some applications to quantum information theory.

“Hilbert’s 10th Problem”

In 1900, the German mathematician David Hilbert outlined 23 major mathematical problems to be studied in the coming century. His ”questions” ranged greatly in topic and precision. They were designed to serve as examples for the kinds of problems whose solutions would lead to the furthering of disciplines in mathematics.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
