Surface links with free abelian link groups
Inasa Nakamura
It is known that if a classical link group is a free abelian group, then its rank is at most two. It is also known that a -component 2-link group () is not free abelian. In…
Unknotting surface links which are coverings of a trivial torus knot
Inasa Nakamura
We consider surface links in the 4-space which are presented by the form of simple branched coverings over the standard torus, which we call torus-covering links. In this paper, we…
Braiding surface links which are coverings over the standard torus
Inasa Nakamura
We consider a surface link in the 4-space which can be presented by a simple branched covering over the standard torus, which we call a torus-covering link. Torus-covering links in…
Surface links which are coverings over the standard torus
Inasa Nakamura
We introduce a new construction of a surface link in the 4-space. We construct a surface link as a branched covering over the standard torus, which we call a torus-covering link. W…
