Bypass attachments and homotopy classes of 2-plane fields in contact topology
Yang Huang
We use the generalized Pontryagin-Thom construction to analyze the effect of attaching a bypass on the homotopy class of the contact structure. In particular, given a 3-dimensional…

A proof of the classification theorem of overtwisted contact structures via convex surface theory
Yang Huang
In 1989, Y. Eliashberg proved that two overtwisted contact structures on a closed oriented 3-manifold are isotopic if and only if they are homotopic as 2-plane fields. We provide a…
