On subcritically Stein fillable 5-manifolds

Fan Ding, Hansjörg Geiges, Guangjian Zhang

We make some elementary observations concerning subcritically Stein fillable contact structures on 5-manifolds. Specifically, we determine the diffeomorphism type of such contact m…

Seifert fibrations of lens spaces

Hansjörg Geiges, Christian Lange

We classify the Seifert fibrations of any given lens space L(p,q). We give an algorithmic construction of a Seifert fibration of L(p,q) over the base orbifold S^2(m,n) with the cop…

Legendrian lens space surgeries

Hansjörg Geiges, Sinem Onaran

We show that every tight contact structure on any of the lens spaces $L (n s^{2} - s + 1, s^{2})$ with $n \geq 2$ , $s \geq 1$ , can be obtained by a single Legendrian surgery along a suitable Le…
