Background on my Research Area

(Return to contents list)

I work in the subject of non-commutative algebra. Broadly speaking, this subject is about solving systems of "polynomial" equations where the solutions are functions (typically differential operators or matrices, etc). This means that we cannot assume that the variables in the equations commute with each other. Such equations arise in the theory of quantum mechanics, statistical mechanics, physics, etc.

The problem of solving a system of equations in non-commutative algebra may be translated to one involving an algebra over a field, and the representation theory (or module theory) of that algebra. My research is in the subarea of non-commutative algebraic geometry, which is about using geometric methods to understand the algebra and its representation theory that arise in this way.

The originators of this kind of non-commutative algebraic geometry are Michael Artin, John Tate and Michel Van den Bergh through work they did in the late 1980's. The subject has grown through the work of these people and of S. Paul Smith, Toby Stafford, Thierry Levasseur, Lieven Le Bruyn and James Zhang to name a few. New ideas and theories are continually being presented, and the research in this subject has grown considerably since the late 1980's. My publication list is below.

Noncommutative Algebraic Geometry, Representation Theory and their Interactions

(Return to contents list)

I am the Director of the UTA research group Noncommutative Algebraic Geometry, Representation Theory and their Interactions, which consists of myself, Dr. Dimitar Grantcharov (co-director) and our Ph.D. students. Currently, the Ph.D. students in the group are: Padmini Veerapen, Justin Ahrens, Thomas Ferguson, Richard Chandler, John Griffis, Yousef Alkhezi and Andrew Cavaness. The group's focus is the study of modules (representations) over an algebra studied from the viewpoint of algebraic geometry, and seeing how these 2 topics feed off each other. Many of these ideas are discussed in the AGANT Seminar organized by myself, and in the local UTA seminar, Representations and Geometry Seminar, organized by D. Grantcharov and co-organized by myself.

Brief Biography

(Return to contents list)

I obtained my Mathematics Ph.D. in 1993 from the University of Washington (Mathematics) under the supervision of S. Paul Smith. The University of Washington is in Seattle, WA, U.S.A.
I obtained my Mathematics bachelor degree in 1986 from the University of Warwick (Mathematics), which is in the Midlands in England.
I spent 6 months of my last academic year of my PhD in the Department of Mathematics of the University of Auckland, in Auckland, New Zealand.

After graduating from Warwick, I was a high school teacher in greater London for one academic year, after which I began my Ph.D.
After getting my Ph.D, I worked for 2 years at the University of Southern California (Mathematics) in Los Angeles, CA, U.S.A.; and then for one year at the University of Antwerp in Antwerp, Belgium; and then for 2 years at the University of Oregon ( Mathematics ) in Eugene, OR, U.S.A. In August 1998, I began working in the Mathematics Department of the University of Texas at Arlington in Arlington, Texas, where I am now a (full) professor.
