# Number Theory Seminar

Tuesday, September 13, 2022 — 2:30 PM EDT

Kevin Hare, Department of Pure Mathematics, University of Waterloo

"Matrix based number system"

Most number systems are of the form $a_k d^k + a_{k-1} d^{k-1} + … + a_0$ where the $a_i$ are taken from a finite set of digits, and $d$ is the base of the number system.

In this talk we will discuss what happens if $d$ is taken to be a $n \times n$ Jordan block and $a_i$ are taken to be vectors.

The format of this seminar will be a shortish presentation, followed by timbits, followed by either discussion of open questions, or discussion technical details, as dictated by the audience.

This seminar will be held jointly online and in person:

• Room: MC 5479
• Zoom information: Meeting ID: 920 8745 1872; Passcode: 412833
