Abstract

The Jones-Wenzl idempotent plays a vital role in quantum invariants of 33-manifolds and the colored Jones polynomial; it also serves as a useful tool for simplifying computations and proving theorems in knot theory. The relative Kauffman bracket skein module (RKBSM) for surface II-bundles and manifolds with marked boundaries have a well understood algebraic structure due to the work of J. H. Przytycki and T. T. Q. L\^e. It has been well documented that the RKBSM of the II-bundle of the annulus and the twisted II-bundle over the M\"obius band have distinct algebraic structures coming from the II-bundle structures. This paper serves as an introduction to studying the trace of Jones-Wenzl idempotents in the Kauffman bracket skein module (KBSM) of the twisted II-bundle of unorientable surfaces. We will give various results on Jones-Wenzl idempotents in the KBSM of the twisted II-bundle over the M\"obius band when it is closed through the crosscap of the M\"obius band. We will also uncover analog properties of Jones-Wenzl idempotents in the KBSM of the twisted II-bundle over the M\"obius band with the preservation of the II-bundle structure that differ from the KBSM of Ann×IAnn \times I.
