Non smooth dynamics and tipping in climate models
2025-03-19
Models for climate often have many time and length scales which means that the dynamical equations that govern their behaviour can best be described in terms of non-smooth differential equations. These equations have very different behaviour from smooth systems, with very rich dynamics and... The number and nature of subgroups of the symmetric group
2025-04-09
The symmetries of any object are described by a group, so it is natural to ask: What does a random group look like? This talk will start with a brief survey of how we might go about counting various algebraic structures. We'll then go on to see what a random group might be, in various...
