Triviality of a surface-link with meridian-based free fundamental group
arXiv:1804.04269
Abstract
It is proved that every disconnected surface-link with meridian-based free fundamental group is a trivial (i.e., an unknotted-unlinked) surface-link. This result is a surface-link version of the author's recent announcement result on smooth unknotting of a surface-knot.
