Classification of ribbon 2-knots of 1-fusion with length up to six

摘要

We classify oriented ribbon 2-knots of 1-fusion with length up to six. We show the difference by: the Alexander polynomial; the trace set, which is obtained from the representations of the knot group to SL(2, C); the twisted Alexander polynomial. (c) 2020 Elsevier B.V. All rights reserved.
