Generalized crossing changes in satellite knots
Cheryl Balm
We show that if K is a satellite knot which admits a generalized cosmetic crossing change of order q with |q| \geq 6, then K admits a pattern knot with a generalized cosmetic cross…
Infinitely many small exotic Stein fillings
Selman Akbulut, Kouichi Yasui
We show that there exist infinitely many simply connected compact Stein 4-manifolds with b_2=2 such that they are all homeomorhic but mutually non-diffeomorphic, and they are Stein…
Gluck twisting 4-manifolds with odd intersection form
Selman Akbulut, Kouichi Yasui
We give a simple criterion when a Gluck twisting an odd smooth 4-manifold along a 2-sphere does not change its diffeomorphism type. We obtain this by handlebody techni…
Embedding Seifert manifolds in S^4
Andrew Donald
Using an obstruction based on Donaldson's theorem on the intersection forms of definite 4-manifolds, we determine which connected sums of lens spaces smoothly embed in S^4. We also…
