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…

On the Dax invariants of $S^{2}$ -bundles over surfaces

Qizheng You

This paper studies the nontrivial orientable $S^{2}$ -bundle $Σ ⋉ S^{2}$ over a closed surface $Σ$ of genus $g \geq 1$ . We have three main results as follows. We construct the rela…
