Unknotting number and number of Reidemeister moves needed for unlinking
link diagram Reidemeister move Hass-Nowik knot diagram invariant
2011/2/22
Using unknotting number, we introduce a link diagram invariant of Hass and Nowik type, which changes at most by 2 under a Reidemeister move. As an application,we show that a certain infinite sequence ...
Recent studies emphasize that an empirical relation between the stellar mass of galaxies and
the mass of their host dark matter subhaloes can predict the clustering of galaxies and its
evolution wit...
