Title: Multiplicative structure of Kauffman bracket skein module quantizations
Authors: Doug Bullock and Jozef H. Przytycki

Abstract: We describe, for a few small examples, the Kauffman bracket
skein algebra of a surface crossed with an interval. If the surface is a punctured torus
the result is a quantization of the symmetric algebra in three variables (and an algebra
closely related to a cyclic quantization of U(so(3)). For a torus without boundary we
obtain a quantization of ``the symmetric homologies" of a torus (equivalently, the
coordinate ring of the SL(2,C)-character variety of Z oplus Z). Presentations are also
given for the four punctured sphere and twice punctured torus. We conclude with an
investigation of central elements and zero divisors.
