Exotic disks and singular instanton Floer homology
Irving Dai, Abhishek Mallick, Masaki Taniguchi
We show that singular instanton Floer homology with the Chern--Simons filtration can be used to produce exotic pairs of slice disks. We moreover construct a strongly invertible $\m…

On absolutely exotic diffeomorphisms of 4-manifolds
Hokuto Konno, Abhishek Mallick, Masaki Taniguchi
We prove that there exist infinitely many contractible compact smooth -manifolds that admit absolutely exotic diffeomorphisms of infinite order in .…
