Maximal Thurston-Bennequin number and reducible Legendrian surgery
Kouichi Yasui
We give a method for constructing a Legendrian representative of a knot in which realizes its maximal Thurston-Bennequin number under a certain condition. The method utilizes…
Nonexistence of Stein structures on 4-manifolds and maximal Thurston-Bennequin numbers
Kouichi Yasui
For a 4-manifold represented by a framed knot in , it has been well known that the 4-manifold admits a Stein structure if the framing is less than the maximal Thurston-Bennequ…
Corks, exotic 4-manifolds and knot concordance
Kouichi Yasui
We show that, for each integer n, there exist infinitely many pairs of n-framed knots representing homeomorphic but non-diffeomorphic (Stein) 4-manifolds, which are the simplest po…
Contact 5-manifolds admitting open books with exotic pages
Selman Akbulut, Kouichi Yasui
We construct a contact 5-manifold supported by infinitely many distinct open books with the identity monodromy and pairwise exotic Stein pages (i.e. pages are pairwise homeomorphic…
