Constraints on Lefschetz fibrations with four-dimensional fibers from Seiberg-Witten theory

Hokuto Konno, Jianfeng Lin, Anubhav Mukherjee +1

We establish constraints on the topology of smooth Lefschetz fibrations with $4$ -dimensional fibers, by studying the family Bauer-Furuta invariant. To compute this invariant, we an…

On absolutely exotic diffeomorphisms of 4-manifolds

Hokuto Konno, Abhishek Mallick, Masaki Taniguchi

We prove that there exist infinitely many contractible compact smooth $4$ -manifolds $C$ that admit absolutely exotic diffeomorphisms of infinite order in $π_{0} (Diff (C))$ . B…
