One internal stabilization is enough for resolving self-referential tubes
Qizheng You
This paper shows that one internal stabilization is enough to resolve all the self-referential tubes on an embedding. As an application, this paper gives a complete isotopy classif…

Examples of hyperbolic spaces without the properties of quasi-ball or bounded eccentricity
Qizheng You, Jiawen Zhang
In this note, we present examples of non-quasi-geodesic metric spaces which are hyperbolic (i.e., satisfying the Gromov's -point condition) while the intersection of any two met…
