Stably exotic fillings of 3-manifolds

Daniel Kasprowski, Patrick Orson, Mark Powell +1

We investigate which 3-manifolds bound 4-manifolds that are homeomorphic but not stably diffeomorphic, where stabilising means taking connected sum with copies of $S^{2} \times S^{2}$ .…

Homotopy classification of $4$ -manifolds with $3$ -manifold fundamental group

Jonathan Hillman, Daniel Kasprowski, Mark Powell +1

We give a criterion on a group $π$ and a homomorphism $w : π \to C_{2}$ under which closed $4$ -manifolds with fundamental group $π$ and orientation character $w$ are classified u…

Multiple addition, deletion and restriction theorems for hyperplane arrangements

Takuro Abe, Hiroaki Terao

In the study of free arrangements, the most useful result to construct/check free arrangements is the addition-deletion theorem. Recently, the multiple version of the addition theo…
