Summary of Proposal for Public Release, 2007

(Submitted to the NSERC)

Why are mathematicians fascinated by the whole numbers? Certainly not because of the beauty inherent in staring at numbers such as 9,465,438. Neither is it due to the difficulty in figuring out that 9,465,438 is 2x3x1,577,573. The true reason is that the whole numbers are surprisingly deep, and the study of whole numbers, also known as "number theory", forced us to better understand, and indeed develop, many other useful and beautiful techniques, concepts and ideas. Number theory just seems to be related to everything.

Likewise, though on a smaller scale, many knot theorists such as myself care little about shoelaces, yet care a lot about the unexpected ways by which the study of knotted shoelaces is intricately and deeply related to such a priori remote subjects as 3-dimensional manifolds, hyperbolic geometry, quantum field theory, differential geometry, Lie theory and representation theory, quantum algebra, combinatorics, homological algebra and sophisticated algorithmics.

My research for this project will concentrate on the further elaboration of these unexpected links, using both analytical and computational tools. My primary goal will be to complete our understanding of the relationship between algebra and the so-called "Kontsevich integral of knotted graphs"; I expect this will benefit knot theory via the tools and techniques of "algebraic knot theory", and I expect this will benefit algebra by providing a unified framework for the study of all quantum groups.

I tend to write expositions and give expository talks, draw pictures and write computer programs. Thus much of my work in this project will end up finding its way to my already-comprehensive web site, at http://www.math.toronto.edu/~drorbn/.
