Showing distinctness of surface links by taking 2-dimensional braids

Geometric Topology 2015-10-19 v2

Abstract

For an oriented surface link SS, we can take a satellite construction called a 2-dimensional braid over SS, which is a surface link in the form of a covering over SS. We demonstrate that 2-dimensional braids over surface links are useful for showing the distinctness of surface links. We investigate non-trivial examples of surface links with free abelian group of rank two, concluding that their link types are infinitely many.
