In quantum mechanics d-partite systems are presented by d-mode tensors.Unentangled states are rank one tensors. Entangled states can be characterized their rank > 1, their spectral norm 1 or their nuclear norm > 1. In this talk I will discuss...

I will describe recent joint work with Jeroen Sijsling, Drew Sutherland, John Voight and Dan Yasaki on genus 2 curves over Q. Our work has three primary goals: (1) produce an extensive table of genus 2 curves and their associated invariants; (2)...

The inmate assignment project is a highly successful prescriptive analytics project. It was conducted in close collaboration with the PA Dept. of Corrections, took five years from start to successful implementation. Our novel Inmate Assignment...

The Selected Areas in Cryptography (SAC) conference series was initiated in 1994, when the first event was held at Queen’s University in Kingston. The SAC conference has been held annually since 1994 in various Canadian locations, including Burnaby...

All standard regression models have assumptions that must be verified for the model to have power to test hypotheses and to make accurate predictions. This course will emphasize methods for assessing and satisfying the linearity and additivity...

A video of this event is available on mathtube.org. Class number of a number field is one of the fundamental and mysterious objects in algebraic number theory and related topics. I will discuss the class numbers of some quadratic fields. More...

First we introduce some results about certain simple diophantine equations involving linear recurrence sequences. Then we present 2 applications. The first application involves the so-called Orbit Intersection Problem for the arithmetic dynamics of...

A video of this event is available on mathtube.org. In this talk, I will give a survey of recent work I have done—some published, some unpublished—on the historical, mathematical, and philosophical problems related to the assignment of "sizes" to...
