14 November: Mathematicians often like to think of maths as objective. On Friday 14th at 12 pm in N4.01, science communicator Hana Ayoob joins us to discuss how the fact that humans do maths means that the ways maths is developed, used, and communicated are not inherently neutral. A Taylors sandwich lunch will be provided, as at all Friday Mathematrix events.
Do you work indoors, live or work in or near Oxford, are aged 23–65, and have trouble sleeping?
Researchers at the University of Oxford are running a study to understand how a new light-based behavioural intervention can improve poor sleep.
Take part from home or work as you go about your daily routine. You’ll be supported by a sleep expert to reach simple, achievable goals.

Improving acylindrical actions on trees
Will Cohen
(Cambridge)
Abstract
Loosely speaking, an action of a group on a tree is acylindrical if long enough paths must have small stabilisers. Groups admitting such actions form a natural subclass of acylindrically hyperbolic groups, and interesting an feature of acylindrical actions on trees is that many interesting properties are inherited from their vertex stabilisers. In order to make use of this, it is important to have some degree of control over these stabilisers. For example, can we ask for these stabilisers to be finitely generated, or even malnormal (or finite-height)? Even stronger, if our group is hyperbolic, can we ask for the stabilisers to be quasiconvex?
In this talk, I will introduce acylindrical actions and some stronger and related concepts, and discuss a method known as the Dunwoody—Sageev resolution that we can use to move between these concepts and provide positive answers to the above questions in some cases.
