TITLE Legendrians in the boundary of subcritical Stein manifolds and exotic Stein structure II
ABSTRACT This is a second part of ongoing learning seminars on Legendrian boundary of subcritical manifolds and exotic Stein structure.
Weinstein 4-manifolds can be obtained by attaching critical handles on the boundary of subcritical Stein manifold.
We review Ekholm-Ng's recipe of DGA for Legendrians in the boundary of subcritical Stein manifold.
As an application, we also construct an exotic Stein structure on 8-dimensional Euclidean space
