Lawson's foliation is, among other codimension 1 foliations,
the first one which was found on S^5 (around 1970). Later on, ALberto Verjovsky posed
questions (around 2000) whether if Lawson's one or some modified ones admit leafwise
comple structures or leafwise symplectic structures. In this talk the second one is answered
affirmatively.
It seems not so common for Stein manifolds to admit an end-periodic symplectic structure,
while the cubic Fermat surface does. We see its construction and as an application we obtain
the affirmative answer to the above question for leafwise symplectic structure.
The arguments also apply with minor modifications to two other cases of simple elliptic
hypersurface singularities.
If the time allows, end-periodic symplectic structures on globally convex symplectic
manifolds are discussed.
