Skein modules at the 4th roots of unity
نویسنده
چکیده
The Kauffman bracket skein modules, S(M,A), have been calculated for A = ±1 for all 3-manifolds M by relating them to the SL2(C)-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).

The skein module of torus knots complements
We compute the Kauffman skein module of the complement of torus knots in S3. Precisely, we show that these modules are isomorphic to the algebra of Sl(2, C)-characters tensored with the ring of Laurent polynomials. Skein modules were introduced indenpendantly by V. Turaev in 1988 and J. Przytycki in 1991 (see [TU88, HP92]) as a C[A±1]-module associated to a 3-manifold M generated by banded link...

Algebra Situs is a branch of mathematics which has its roots in Jones’ construction of his polynomial invariant of links and Drinfeld’s work on quantum groups. It encompasses the theory of quantum invariants of knots and 3-manifolds, algebraic topology based on knots, operads, planar algebras, q-deformations, quantum groups, and overlaps with algebraic geometry, non-commutative geometry and sta...

متن کاملInductive Construction of Nilpotent Modules of Quantum Groups at Roots of Unity
The purpose of this paper is to prove that we can construct all finite dimensional irreducible nilpotent modules of type 1 inductively by using Schnizer homomorphisms for quantum algebra at roots of unity of type An, Bn, Cn, Dn or G2.
متن کاملNilpotent Representations of Classical Quantum Groups at Roots of Unity
Properly specializing the parameters in “Schnizer modules”, for type A,B,C and D, we get its unique primitive vector. Then we show that the module generated by the primitive vector is an irreducible highest weight module of finite dimensional classical quantum groups at roots of unity.
