Embedding complexes into pseudomanifolds
Kasia Jankiewicz, Kevin Schreve
We show that for every finite -dimensional simplicial complex is a deformation retract of a -dimensional pseudomanifold with boundary. Moreover, it embeds as a…
Cubical small-cancellation quotients of non-products
Macarena Arenas, Kasia Jankiewicz, Daniel T. Wise
We show that if is a compact nonpositively curved cube complex which is a non-product, then has a proper quotient that is 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…
Centers of Artin groups defined on cones
Kasia Jankiewicz, MurphyKate Montee
We prove that the Center Conjecture passes to the Artin groups whose defining graphs are cones, if the conjecture holds for the Artin group defined on the set of the cone points. I…
Products of free groups inside graph braid groups
Kasia Jankiewicz, Kevin Schreve
Given a graph and a number , the associated graph braid group is the fundamental group of the unordered configuration space of points on . Świątkows…
Generalized Residual Finiteness of Groups
Nic Brody, Kasia Jankiewicz
A countable group is residually finite if every nontrivial element can act nontrivially on a finite set. When a group fails to be residually finite, we might want to measure how dr…
Profinite properties of algebraically clean graphs of free groups
Kasia Jankiewicz, Kevin Schreve
We prove that for every prime algebraically clean graphs of groups are virtually residually -finite and cohomologically -complete. We also prove that they are cohomologic…
Hyperbolicity in non-metric cubical small-cancellation
Macarena Arenas, Kasia Jankiewicz, Daniel T. Wise
Given a non-positively curved cube complex , we prove that the quotient of defined by a cubical presentation satisfying sufficient n…
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…
The -conjecture implies the center conjecture for Artin groups
Kasia Jankiewicz, Kevin Schreve
In this note, we prove that the -conjecture for Artin groups implies the center conjecture for Artin groups. Specifically, every Artin group without a spherical factor that…
Cubulating Small Cancellation Free Products
Kasia Jankiewicz, Daniel T. Wise
We give a simplified approach to the cubulation of small-cancellation quotients of free products of cubulated groups. We construct fundamental groups of compact nonpositively curve…
The boundary rigidity of lattices in products of trees
Kasia Jankiewicz, Annette Karrer, Kim Ruane +1
We show that every group acting freely and vertex-transitively by isometries on a product of two regular trees of finite valence is boundary rigid. That means that every CAT(0) spa…
Splittings of triangle Artin groups
Kasia Jankiewicz
We show that a triangle Artin group where splits as an amalgamated product or an HNN extension of finite rank free groups, provided that either $…
Right-angled Artin subgroups of Artin groups
Kasia Jankiewicz, Kevin Schreve
The Tits Conjecture, proved by Crisp and Paris, states that squares of the standard generators of any Artin group generate an obvious right-angled Artin subgroup. We consider a lar…
A curiously cubulated group
Kasia Jankiewicz, Daniel T. Wise
We construct a finitely generated 2-dimensional group that acts properly on a locally finite CAT(0) cube complex but does not act properly on a finite dimensional CAT(0) cube compl…
Residual finiteness of certain 2-dimensional Artin groups
Kasia Jankiewicz
We show that many -dimensional Artin groups are residually finite. This includes -generator Artin groups with labels except for for any . As a…
Groups acting on CAT(0) cube complexes with uniform exponential growth
Radhika Gupta, Kasia Jankiewicz, Thomas Ng
We study uniform exponential growth of groups acting on CAT(0) cube complexes. We show that groups acting without global fixed points on CAT(0) square complexes either have uniform…
Lower bounds on cubical dimension of groups
Kasia Jankiewicz
For each we construct examples of finitely presented small cancellation groups that do not act properly on any -dimensional CAT(0) cube complex.
Virtually Fibering Right-Angled Coxeter Groups
Kasia Jankiewicz, Sergey Norin, Daniel T. Wise
We show that certain right-angled Coxeter groups have finite index subgroups that quotient to with finitely generated kernels. The proof uses Bestvina-Brady Morse theor…
Cocompactly cubulated 2-dimensional Artin groups
Jingyin Huang, Kasia Jankiewicz, Piotr Przytycki
We give a necessary and sufficient condition for a 2-dimensional or a three-generator Artin group to be (virtually) cocompactly cubulated, in terms of the defining graph of …
Incoherent Coxeter Groups
Kasia Jankiewicz, Daniel T. Wise
We use probabilistic methods to prove that many Coxeter groups are incoherent. In particular, this holds for Coxeter groups of uniform exponent > 2 with sufficiently many generator…
A sharper threshold for random groups at density one-half
Moon Duchin, Kasia Jankiewicz, Shelby C. Kilmer +3
In the density model of random groups, we consider presentations with any fixed number m of generators and many random relators of length l, sending l to infinity. If d is a "densi…
The fundamental theorem of cubical small cancellation theory
Kasia Jankiewicz
We give a new proof of the main theorem in the theory of C(6) small cancellation complexes. We prove the fundamental theorem of cubical small cancellation theory for C(9) cubical s…
