Cubical small-cancellation quotients of non-products

Macarena Arenas, Kasia Jankiewicz, Daniel T. Wise

We show that if $X$ is a compact nonpositively curved cube complex which is a non-product, then $π_{1} X$ has a proper quotient that is $π_{1}$ of a cube complex with these same proper…

Cleanliness versus Specialness

Kasia Jankiewicz

We show that the fundamental group of a geometrically clean graph of finite rank free groups does not need to be virtually compact special, answering a question of Wise. This impli…

The $K (π, 1)$ -conjecture implies the center conjecture for Artin groups

Kasia Jankiewicz, Kevin Schreve

In this note, we prove that the $K (π, 1)$ -conjecture for Artin groups implies the center conjecture for Artin groups. Specifically, every Artin group without a spherical factor that…

Splittings of triangle Artin groups

Kasia Jankiewicz

We show that a triangle Artin group $Art_{M N P}$ where $M \leq N \leq P$ splits as an amalgamated product or an HNN extension of finite rank free groups, provided that either $…

Lower bounds on cubical dimension of $C^{'} (1/6)$ groups

Kasia Jankiewicz

For each $n$ we construct examples of finitely presented $C^{'} (1/6)$ small cancellation groups that do not act properly on any $n$ -dimensional CAT(0) cube complex.
