This lunch is hosted by Prof. Dr. Anna Gusakova and Prof. Dr. Angela Stevens, and connects established female mathematicians with those who are at the beginning of their scientific careers. To register, please visit https://indico.uni-muenster.de/event/3364/

A good model describing droplets at thermodynamical equilibrium consists in volume constrained solutions of the surface energy combined with a potential gradient arising from an external potential field. With the main goal of approaching this phenomena in curved ambient spaces, in a work joint with Shrey Aryan (MIT) we prove a first classification of minimizers for a rich family of radial weights. We also provide counter examples to show that, in contrast with the weighted isoperimetric case, stability of centered spheres in general does not imply global minimiality. Time permitting, we will discuss a quantitative sharp stability result based on the previous classification.

Origami is not only an art form but also a subject of mathematical interest, especially due to its geometric design. While traditional origami uses straight folds to create flat surfaces, paper can also be bent into curved, developable surfaces. Curved folding enables new modeling possibilities, though it has been less studied. This talk will introduce the speaker's work on curved folding, including artistic examples and design methods. It will also touch on origami's cultural and engineering aspects, and conclude with a hands-on curved folding workshop.

Abstract: We briefly review the tautological ring of the moduli space of surfaces, before discussing how to define the analogous ring for the moduli space of 3-dimensional handlebodies (and more generally, odd-dimensional manifolds with boundary). We then discuss some sheaf-theoretic methods of probing the structure of this ring. The talk is based on ongoing work that will (hopefully) appear in my PhD thesis this summer.

Join us to learn more about the career and work of Prof. Shirly Geffen. After the talk, there will be time to chat over a coffee together.

Abstract: The ?-category Cond(Ani) of condensed anima combines the homotopy-theoretic direction of anima with the topological space direction of condensed sets. For example, we can recover the shape of a sufficiently nice topological space from the corresponding condensed anima. My talk will focus on a joint refinement of the etale homotopy type and the pro-etale fundamental group of a scheme, realised as an object in Cond(Ani). This is closely related to work of Barwick, Glasman and Haine on exodromy. I will give an overview of results from my dissertation and an ongoing project jointly with Haine, Holzschuh, Lara and Wolf.
