Knot surgery -manifolds without - and -handles
Ju A Lee, Ki-Heon Yun
In this article, we demonstrate that for any positive integer , the knot surgery -manifold has a handle decomposition without - and -handles. Here, represe…
On dissolving knot surgery -manifolds under a -connected sum
Hakho Choi, Jongil Park, Ki-Heon Yun
In this article we prove that, if is a smooth -manifold containing an embedded double node neighborhood, all knot surgery -manifolds are mutually diffeomorphic to e…
On the minimal number of singular fibers in Lefschetz fibrations over the torus
András I. Stipsicz, Ki-Heon Yun
We show that the minimal number of singular fibers in a genus- Lefschetz fibration over the torus is at least . As an application, we show that $N(g, 1) \in \{ 3, 4\…
Lefschetz fibrations on knot surgery -manifolds via Stallings twist
Jongil Park, Ki-Heon Yun
In this article we construct a family of knot surgery -manifolds admitting arbitrarily many nonisomorphic Lefschetz fibration structures with the same genus fiber. We obtain suc…
Families of nondiffeomorphic 4-manifolds with the same Seiberg-Witten invariants
Jongil Park, Ki-Heon Yun
In this article, we show that, at least for non-simply connected case, there exist an infinite family of nondiffeomorphic symplectic 4-manifolds with the same Seiberg-Witten invari…
Lefschetz fibration structures on knot surgery 4-manifolds
Jongil Park, Ki-Heon Yun
In this article we study Lefschetz fibration structures on knot surgery 4-manifolds obtained from an elliptic surface E(2) using Kanenobu knots . As a result, we get an infinite…
