Canadian Abstract Harmonic Analysis Symposium
Date:

Thu, Jul 7, 2016 - Fri, Jul 8, 2016 ## The Life and Numbers of Richard Guy

Speaker:

Hugh Williams
Date:

Tue, Jun 21, 2016
Location:

PIMS, University of Calgary
Conference:

Canadian Number Theory Association 2016 Abstract:

Fifty years ago Richard Kenneth Guy joined the then Department of Mathematics, Statistics and Computer Science at the nascent University of Calgary. Although he retired from the University in 1982, he has continued, even in his 100th year, to come in every day and work on the mathematics that he loves.
Hugh Williams, Richard’s long-time friend and colleague, will share with us a glimpse into the life and research of this most remarkable man. You will not want to miss this inspirational talk!

## Nonlocal equations from various perspectives - lecture 3

Speaker:

Enrico Valdinoci
Date:

Wed, Jun 15, 2016
Location:

PIMS, University of British Columbia
Conference:

PIMS Workshop on Nonlocal Variational Problems and PDEs Abstract:

We would like to give a detailed presentation of some equations which exhibit some nonlocal phenomena. Often, the nonlocal effect is modelled by a diffusive operator which is (in some sense) elliptic and fractional. Natural example arise from probability, geometry, quantum physics, phase transition theory and crystal dislocation dynamics. We will try to discuss some of the mathematical tools that are useful to deal with these problems, explain in detail some of the main motivations, describe some recent results on these topics and list some open problems.

## Operational Research and the Criminal Justice System

Speaker:

Alexander Rutherford
Date:

Wed, Mar 30, 2016
Location:

PIMS, Simon Fraser University
Conference:

Lunchbox Lecture Series Abstract:

The Criminal Justice System is responsible for upholding public safety through the enforcement of laws, the apprehension, prosecution, and judging of suspects, and the administration of community and custodial sentences. It is highly complex, with interactions between police, prosecutors, judges, the court, and correctional services. Effective and efficient administration of justice is important for maintaining public safety.
We present an overview of operational research modelling applied to the Criminal Justice System. Two case studies are considered: a systems dynamics model of the impact of the 2010 impaired driving legislation in British Columbia and a queue network model of the impact of the Truth in Sentencing Act of Canada.

## A glamorous Hollywood star, a renegade composer, and the mathematical development of spread spectrum communications.

Speaker:

Mark Goresky
Date:

Mon, May 30, 2016
Location:

PIMS, University of British Columbia
Conference:

2016 Niven Lecture Abstract:

During World War II Hedy Lamarr, a striking Hollywood actress, together with George Antheil, a radical composer, invented and patented a secret signaling system for the remote control of torpedoes. The ideas in this patent have since developed into one of the ingredients in modern digital wireless communications. The unlikely biography of these two characters, along with some of the more modern developments in wireless communications will be described.

## Bayesian study design for nonlinear systems: an animal disease transmission experiment case study

Speaker:

Rob Deardon
Date:

Tue, May 3, 2016
Location:

PIMS, University of Calgary
Conference:

Lunchbox Lecture Series Abstract:

Experimental design is a branch of statistics focused upon designing experimental studies in a way that maximizes the amount of salient information produced by the experiment. It is a topic which has been well studied in the context of linear systems. However, many physical, biological, economic, financial and engineering systems of interest are inherently non-linear in nature. Experimental design for non-linear models is complicated by the fact that the optimal design depends upon the parameters that we are using the experiment to estimate. A Bayesian, often simulation-based, framework is a natural setting for such design problems. We will illustrate the use of such a framework by considering the design of an animal disease transmission experiment where the underlying goal is to identify some characteristics of the disease dynamics (e.g. a vaccine effect, or the infectious period).

## Multivariable Operator Theory and Dilation Theory

Speaker:

Kenneth R. Davidson
Date:

Tue, Apr 5, 2016
Location:

PIMS, University of Manitoba
Conference:

PIMS-UManitoba Distinguished Lecture Abstract:

This will be a general talk about the role of dilation theory in studying operators on Hilbert space, illustrated in part by some recent work of mine with Raphaël Clouâtre on multivariable operator theory.
