Tight contact structures on some bounded Seifert manifolds with minimal convex boundary

Fan Ding, Youlin Li, Qiang Zhang

We classify positive tight contact structures, up to isotopy fixing the boundary, on the manifolds $N = M (D^{2}; r_{1}, r_{2})$ with minimal convex boundary of slope $s$ and Giroux torsi…
