Shadows, ribbon surfaces, and quantum invariants
Eisermann has shown that the Jones polynomial of a n -component ribbon link L\subset S^3 is divided by the Jones polynomial of the trivial n -component link. We improve this theorem by extending its range of application from links in S^3 to colored knotted trivalent graphs in \#_g(S^2\times S^1) , …
