Positive basis for surface skein algebras.

چکیده
We show that the twisted SL2 skein algebra of a surface has a natural basis (the bracelets basis) that is positive, in the sense that the structure constants for multiplication are positive integers.

On Positivity of Kauffman Bracket Skein Algebras of Surfaces
We show that the Chebyshev polynomials form a basic block of any positive basis of the Kauffman bracket skein algebras of surfaces.
متن کاملSkein theory for the ADE planar algebras
We give generators and relations for the planar algebras corresponding to the E8 subfactor. We also give an explicit basis, and an algorithm to express an arbitrary diagram as a linear combination of basis diagrams. We summarize the analogous results for the other ADE subfactors, which can be obtained by the same methods. © 2009 Elsevier B.V. All rights reserved.
متن کاملMatrix Formulae and Skein Relations for Cluster Algebras from Surfaces
This paper concerns cluster algebras with principal coefficients A•(S,M) associated to bordered surfaces (S,M), and is a companion to a concurrent work of the authors with Schiffler [MSW2]. Given any (generalized) arc or loop in the surface – with or without self-intersections – we associate an element of (the fraction field of) A•(S,M), using products of elements of PSL2(R). We give a direct p...
متن کاملSkein Modules of Links in Cylinders over Surfaces
We define the Conway skein module (M) of ordered based links in a 3-manifold M . This module gives rise to (M)-valued invariants of usual links in M . We determine a basis of the Z[z]-module (Σ× [0,1])/Tor( (Σ× [0,1])), where Σ is the real projective plane or a surface with boundary. For cylinders over the Möbius strip or the projective plane, we derive special properties of the Conway skein mo...
متن کاملSkein algebra of a group
We define for each group G the skein algebra of G. We show how it is related to the Kauffman bracket skein modules. We prove that skein algebras of abelian groups are isomorphic to symmetric subalgebras of corresponding group rings. Moreover, we show that, for any abelian group G, homomorphisms from the skein algebra of G to C correspond exactly to traces of SL(2, C)-representations of G. We al...
