Title: "Reflection Equation Algebra and its applications to Noncommutative Geometry"


Reflection Equation Algebra (REA) is one of the central objects of Braided Geometry.
By Braided Geometry I mean a theory related to a braiding, i.e. a solution to the Quantum
Yang-Baxter Equation. I'll
exhibit properties of the REA related to different types of braidings.

Also, I'll explain the role of the REA in constructing a differential calculus on the enveloping
algebra U(gl(n)). In the case n=2 this calculus leads
to a noncommutative version of
the Minkowski space algebra. Many of
dynamical models of Physics can be generalized to this algebra.

A very amusing fact is that these models are in a sense discrete.

Colloquium coordinators are Prof.dr. A.C.D. van Enter (e-mail : and
Dr. A.V. Kiselev (e-mail: )
