Interests
My research interests are in low (i.e. 3 and 4) dimensional topology,
the Jones polynomial, hyperbolic geometry, mathematical physics,
Chern-Simons theory, string theory, M-theory, enumerative combinatorics,
enumerative algebraic geometry, number theory, quantum topology,
asymptotic analysis, numerical analysis, integrable systems,
motivic cohomology, K-theory, Galois theory, deformation and
geometric quantization.
In my early career, I got interested in TQFT (topological
quantum field theory) invariants of knotted 3-dimensional objects,
such as knots, braids, srting-links or 3-manifolds.
Later on, I became interested in finite type invariants (a code
name for perturbative quantum field theory invariants of knotted
objects).
I studied their axiomatic properties, and related the various
definitions
to each other. A side project was to study the various filtrations of
the
mapping class groups, and to explicitly construct cocycles, using
finite
type invariants.
More recently, I have been studying the colored Jones polynomials of a
knot,
and its limiting geometry and topology. The colored Jones polynomials
is
not a single polynomial, but a sequence of them, which is known to
satisfy
a linear q-difference equation. Writing the equation into an operator
form,
and setting q=1, conjecturally recovers the A-polynomial. The latter
parametrizes out the moduli space of SL(2,C) representation of the knot
complement.
Another relation between the colored Jones polynomial and SL(2,C) (ie,
hyperbolic) geometry is the Volume Conjecture that relates evaluations
of the colored Jones polynomial to the volume of a knot. This and
related
conjectures fall into the problem of proving the existence of
asymptotic
expansions of combinatorial invariants of knotted objects. Most
recently,
I am working on resurgence of formal power series of knotted objects.
Resuregence is a key property which (together the nonvanishing of some
Stokes constant) implies the Volume Conjecture. Resurgence is
intimately
related to Chern-Simons perturbation theory, and produces singularities
of
geometric as well as arithmetic interst. Resurgence seems to be related
to the Grothendieck-Teichmuller group.
In short, my interests are in low dimensional topology, geometry and
mathematical physics.
