Embedding complexes into pseudomanifolds

Kasia Jankiewicz, Kevin Schreve

We show that for $d \geq 2$ every finite $d$ -dimensional simplicial complex is a deformation retract of a $(2 d - 1)$ -dimensional pseudomanifold with boundary. Moreover, it embeds as a…

Finite Stature in Artin groups

Kasia Jankiewicz

We give criteria for a graph of groups to have finite stature with respect to its collection of vertex groups, in the sense of Huang-Wise. We apply it to the triangle Artin groups…

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 $I ¨ _{1} X$ has a proper quotient that is $I ¨ _{1}$ of a cube complex with these same prop…

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…
