Here https://arxiv.org/abs/1702.08715 is a link to the same article that might be a little easier to use.
Link to the abstract: https://arxiv.org/abs/1702.08715
Generally, it is better to link to the abstract than to the PDF. If the paper gets revised the abstract page page's PDF link will point to the latest version of the paper (with links available to prior revisions). The direct PDF link will remain stuck with the old version.
