Smooth concordance of links topologically concordant to the Hopf link
Smooth concordance of links topologically concordant to the Hopf link
It was shown by Jim Davis that a 2-component link with Alexander polynomial one is topologically concordant to the Hopf link. In this paper, we show that there is a 2-component link with Alexander polynomial one that has unknotted components and is not smoothly concordant to the Hopf link, answering …
