Notes. Status designated by symbol “+” denotes that the knot’s innermost trajectory has been observed to follow the precessing common trajectory and symbol “–” denotes that the knot’s innermost trajectory following the precessing common trajectory has not been observed (no observation data available).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
