Generators and relations of direct products of semigroups
TL;DR: In this paper, the authors give necessary and sufficient conditions for the direct product of two semigroups to be finitely generated, and also for their direct product to be presented.
On genus-1 simplified broken Lefschetz fibrations
TL;DR: In this paper, the authors studied monodromy representations of higher sides of genus-1 simplified broken Lefschetz fibrations and determined the diffeomorphism types of the total spaces of these fibrains.
Engel relations in 4-manifold topology
TL;DR: In this paper, the A-B slice problem is shown to admit a homotopy solution, and a new collection of universal surgery problems, defined using ramifications of homotopically trivial links.
