Characterizations of knot groups and knot symmetric quandles of surface-links
Jumpei Yasuda
The knot group is the fundamental group of a knot or link complement. A necessary and sufficient conditions for a group to be realized as the knot group of some link was provided.…

Computation of the knot symmetric quandle and its application to the plat index of surface-links
Jumpei Yasuda
A surface-link is a closed surface embedded in the 4-space, possibly disconnected or non-orientable. Every surface-link can be presented by the plat closure of a braided surface, w…

A plat form presentation for surface-links
Jumpei Yasuda
In this paper, we introduce a method, called a plat form, of describing a surface-link in the 4-space using a braided surface. We prove that every surface-link, which is not necess…
