Algebraically overtwisted tight $3$-manifolds from $+1$ surgeries

Symplectic Geometry 2024-11-01 v2 Geometric Topology

Abstract

We execute Avdek's algorithm to find many algebraically overtwisted and tight 33-manifolds by contact +1+1 surgeries. In particular, we show that a contact 1/k1/k surgery on the standard contact 33-sphere along any positive torus knot with the maximum Thurston-Bennequin invariant yields an algebraically overtwisted and tight 33-manifold, where kk is a positive integer.
