My research interests:
My research interests lie at the interface of mathematical physics, geometry and representation theory,
more specifically in quantum field theory, statistical mechanics,
geometry and low-dimensional topology, and representation theory of quantum groups.
Representation theory of quantum groups and of quantized universal enveloping algebras
is the main algebraic structure behind integrability of most known "non-Gaussian" integrable
models in classical and quantum mechanics, in field theory, and in statistical mechanics.
This direction has many fascinating problems ranging from answering deep questions
in statistical mechanics (in solvable examples, where more tools are available)
to deep structural results in representation theory which are motivated by physical applications.
Representation theory of quantum groups is also
a powerful tool behind constructions of invariants of knots and 3-dimensional manifolds.
Invariants of knots and 3-manifolds can also be obtained by quantizing
classical topological field theories. Such theories are, as a rule, are gauge
invariant (examples are Chern-Simons theory, BF theory, Poisson sigma model and others).
Quantization of such theories involve a lot of modern geometry.
One of the challenges in this direction is to develop semiclassical
quantization of such theories for space time manifolds with boundary.

Most of my publications after 1994 can be found on the arXiv.org..
Here are two unpublished preprints on invariants of knots and quantum groups
which were written in 1987, were circulated by mail, but were never published: Invariants of tangles 1
and Invariants of tangles 2
Here is the preprint (with A. N. Kirillov) where quantum 6j-symbols were introduced and studied: q-6j
The results were published in [A. N. Kirillov and N. Yu. Reshetikhin. Representations of the algebra Uq(sl(2)), q-orthogonal
polynomials and invariants of links. In Infinite-dimensional Lie algebras and
groups (Luminy-Marseille, 1988), pages 285-339. World Sci. Publishing, Teaneck, NJ, 1989] but this volume is difficult to obtain.
