"Counting Circles: Jones Polynomial of Knots, Temperley
Lieb algebras and the root poset
of A_n"
ABSTRACT: Using the simple geometric idea of counting circles
in <<closing up>> certain diagrams,
I
will give an introduction to the Jones polynomial of a knot using Kauffman's
bracket. Then, the same
diagrams will be used to construct the Temperley
Lieb algebra together with a symmetric bilinear form
which also gives the Jones polynomial of a closed braid
representation of a knot or link. If time permits,
I
will finally relate this construction to the positive root poset
of the symmetric group.
