The Department of Materials is organising our postgraduate Open Day for those interested in applying to our postgraduate courses.
During this online event, you will find out more about making a good application, funding, key dates, and more. You will meet current students as well as supervisors, and there will be an opportunity to ask questions during a live Q&A session.
This Michaelmas, the Radcliffe Science Library Wellbeing Programme is back with a range of free activities designed to help you take a break, recharge and connect with others during a busy term.
From weekly hot drinks and LEGO Lunches to board games, crafts and therapy dogs, there’s something to help you step away from your studies for a little while.
About the Role
We are seeking an EDI Officer to play a key role in turning the Mathematical Institute’s equality, diversity and inclusion (EDI) strategy into meaningful and measurable change. You will support a range of initiatives designed to foster a welcoming, respectful and supportive environment for our staff and students, with a particular focus on implementing, monitoring and evaluating our Athena Swan Action Plan.
Multiparameter persistent homology (MPH) associates to a vector-valued filter function on a simplicial complex a multiparameter persistence module. In this talk, I will present recent joint work with Heather Harrington and Ulrike Tillmann on the inverse problem for MPH: given a persistence module, what can we say about the data that generated it? To study the geometry of the fibers of MPH, we equip both the space of filters and the moduli space of essentially finite persistence modules with natural stratifications that are preserved by the map. Over each stratum in its image, MPH restricts to a trivial fiber bundle whose fiber is a polyhedral complex. We also bound the dimension of MPH fibers in terms of multigraded Betti numbers, recovering the one-parameter bound of Leygonie and Tillmann as a special case.
