Theorem 1.2. Consider four-manifolds where
- •
is the union of one-handles;
- •
is obtained from by attaching two-handles along a framed link ;
- •
is obtained from by attaching three-handles along spheres ;
- •
be obtained from by attaching some four-handles.
Consider also a framed link , and view as a link in . Then, the skein lasagna module is isomorphic to the quotient of the cabled skein lasagna module by coequalizing relations coming from the 3-handles as in Theorem 1.1. (See Theorem 3.10 for a more precise statement.)
