Algebraic overtwistedness of contact $(+ 1)$ -surgeries via augmented Floer theories

Russell Avdek, Youlin Li, Zhengyi Zhou

We prove that contact $(+ 1)$ -surgery along a Legendrian $n$ -sphere $Λ \subset (S^{2 n + 1}, ξ_{std})$ with \[ \mathrm{tb}(Λ)\ne (-1)^{\frac{n(n-1)}{2}+1} \] has vanishi…

Characterizing slopes for Legendrian knots

Youlin Li, Chi Zhang

We establish a criterion relating smooth and contact characterizing slopes under a uniqueness assumption. Let $L$ be a Legendrian representative of a knot $K \subset S^{3}$ with stand…
