Relative Kauffman bracket skein module
= Relative Kauffman bracket skein module
The relative skein <module> fixes finitely many framed endpoints on the boundary of a 3-manifold and uses properly embedded framed tangles with those endpoints. Local <Kauffman bracket> relations are imposed away from the boundary. Gluing compatible endpoint sets composes tangles; a rectangle cylinder with n endpoints on each horizontal side gives the <Temperley-Lieb diagram algebra>.
