Speaker: Mai Gehrke (Université Côte d'Azur, Nice, France)
A presheaf over a meet semilattice gives rise, via a construction introduced by Grothendieck, to a simple algebraic structure: it is based on the local sections and is equipped with the operation sometimes called restriction: given local sections \( s \) and \( t \), the restriction of \( t...

Fitness and subfitness via interior and closure operators
2026-06-26
Speaker: João Areias
We start by rephrasing some well-known characterizations of fit and subfit locales in terms of closure and interior operators on the system of sublocales. Using these characterizations, we are able to extend the notions of fitness and subfitness to a more general setting. This approach not...

From phase separation in heterogeneous media to learning training schemes for image denoising
2026-10-29
Speaker: Irene Fonseca (Carnegie Mellon University, USA)
What do these two themes have in common? Both are treated variationally, both deal with energies of different dimensionalities, concepts of geometric measure theory prevail in both, and higher order penalizations are considered. Will learning training schemes for choosing these...
