SKEIN MODULES AT THE 4TH ROOTS OF UNITY
Abstract
The Kauffman bracket skein modules, , have been calculated for A=±1 for all 3-manifolds M by relating them to the
-character varieties. We extend this description to the case when A is a 4th root of 1 and M is either a surface×[0,1] or a rational homology sphere (or its submanifold).
