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…

$I ¨ _{1}$ -injective bounding and application to 3- and 4-manifolds

Jianfeng Lin, Zhongzi Wang

Suppose a closed oriented $n$ -manifold $M$ bounds an oriented $(n + 1)$ -manifold. It is known that $M$ $I ¨ _{1}$ -injectively bounds an oriented $(n + 1)$ -manifold $W$ . We prove that $Ï_1…

The monodromy diffeomorphism of weighted singularities and Seiberg--Witten theory

Hokuto Konno, Jianfeng Lin, Anubhav Mukherjee +1

We prove that the monodromy diffeomorphism of a complex 2-dimensional isolated hypersurface singularity of weighted-homogeneous type has infinite order in the smooth mapping class…
