Let A be a commutative algebraic group dened over a number field K. For a prime } in K where A has good reduction, let N};n be the number of n-torsion F}-rational points of the reduction of A modulo } where F} is the residue field of } and n is a positive integer. When A is of dimension one

A classical result of Glimm from 1961 asserts that the irreducible

representations of a given separable C*-algebra A are classifiable by real

numbers up to unitary equivalence if and only if A is type I. In 2008,

Kerr-Li-Pichot and, independently, Farah proved that when A is not type I,

The aim of this talk is to build up as much intuition as time allows about all things simplicial. This includes n-simplices, simplicial complexes and their polytopes, abstract simplicial complexes and the geometric realisation of such abstract objects.

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 Office of Indigenous Relations.
