Exotic codimension-1 submanifolds in 4-manifolds and stabilizations
Hokuto Konno, Anubhav Mukherjee, Masaki Taniguchi
In a small simply-connected closed 4-manifold, we construct infinitely many pairs of exotic codimension- submanifolds with diffeomorphic complements that remain exotic after any…
Homological instability for moduli spaces of smooth 4-manifolds
Hokuto Konno, Jianfeng Lin
We prove that homological stability fails for the moduli space of any simply-connected closed smooth 4-manifold in any degree of homology, unlike what happens in all dimensions $\n…
A note on generalized Thurston--Bennequin inequalities
Nobuo Iida, Hokuto Konno, Masaki Taniguchi
We give a generalized Thurston--Bennequin-type inequality for links in using a Bauer--Furuta-type invariant for 4-manifolds with contact boundary. As a special case, we also…
Diffeomorphisms of 4-manifolds with boundary and exotic embeddings
Nobuo Iida, Hokuto Konno, Anubhav Mukherjee +1
We define family versions of the invariant of 4-manifolds with contact boundary due to Kronheimer and Mrowka and use these to detect exotic diffeomorphisms of 4-manifolds with boun…
Dehn twists and the Nielsen realization problem for spin 4-manifolds
Hokuto Konno
We prove that, for a closed oriented smooth spin 4-manifold with non-zero signature, the Dehn twist about a - or -sphere in is not homotopic to any finite order…
