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

Abstract

We execute Avdek's algorithm to find many algebraically overtwisted and tight $3$-manifolds by contact $+1$ surgeries. In particular, we show that a contact $1/k$ surgery on the standard contact $3$-sphere along any positive torus knot with the maximum Thurston-Bennequin invariant yields an algebraically overtwisted and tight $3$-manifold, where $k$ is a positive integer.
