A factorization of the Conway polynomial and covering linkage invariants
Tatsuya Tsukamoto, Akira Yasuhara
J.P. Levine showed that the Conway polynomial of a link is a product of two factors: one is the Conway polynomial of a knot which is obtained from the link by banding together the…

The fourth skein module and the Montesinos-Nakanishi conjecture for 3-algebraic links
Jozef H. Przytycki, Tatsuya Tsukamoto
We study the concept of the fourth skein module of 3-manifolds, that is a skein module based on the skein relation b_0L_0 + b_1L_1 + b_2L_2 + b_3L_3 = 0 and a framing relation L^{(…

A criterion for almost alternating links to be non-splittable
Tatsuya Tsukamoto
We give a sufficient condition for an almost alternating link diagram to represent a non-splittable link. The main theorem gives us a way to see if a given almost alternating link…
