Extra-large type Artin groups are hierarchically hyperbolic

Mark Hagen, Alexandre Martin, Alessandro Sisto

We show that Artin groups of extra-large type, and more generally Artin groups of large and hyperbolic type, are hierarchically hyperbolic. This implies in particular that these gr…

Projection complexes and quasimedian maps

Mark Hagen, Harry Petyt

We use the projection complex machinery of Bestvina--Bromberg--Fujiwara to study hierarchically hyperbolic groups. In particular, we show that if the group has a BBF colouring and…

A remark on thickness of free-by-cyclic groups

Mark Hagen

Let $F$ be a free group of positive, finite rank and let $Φ \in A u t (F)$ be a polynomial-growth automorphism. Then $F ⋊_{Φ} Z$ is strongly thick of order $η$ , where $η$ is…

Dehn filling Dehn twists

François Dahmani, Mark Hagen, Alessandro Sisto

Let $Σ_{g, p}$ be the genus-- $g$ oriented surface with $p$ punctures, with either $g > 0$ or $p > 3$ . We show that $M C G (Σ_{g, p}) / D T$ is acylindrically hyperbolic where $D T$ is the norma…

Hardware Aspects, Modularity and Integration of an Event Mode Data Acquisition and Instrument Control for the European Spallation Source (ESS)

Thomas Gahl, Mark Hagen, Richard Hall-Wilton +7

The European Spallation Source (ESS) in Lund, Sweden is just entering the construction phase with 3 neutron instruments having started in its design concept phase in 2014. As a col…
