Pseudo-Legendrian and Legendrian Simplicity of Links in 3-Manifolds
Patricia Cahn, Rima Chatterjee, Vladimir Chernov
We construct infinite families of non-simple isotopy classes of links in overtwisted contact structures on -bundles over surfaces. These examples include: (1) a pair of Legend…

Cable links of uniformly thick knot types
Rima Chatterjee, John B. Etnyre, Hyunki Min +1
In this paper, we study Legendrian realizations of cable links of knot types that are uniformly thick but not Legendrian simple, extending prior work of Dalton, the second author,…

Existence and construction of non-loose knots
Rima Chatterjee, John B. Etnyre, Hyunki Min +1
In this paper we give necessary and sufficient conditions for a knot type to admit non-loose Legendrian and transverse representatives in some overtwisted contact structure, classi…
