Mirror symmetry for generalized Kummer varieties – Justin Sawon (University of North Carolina at Chapel Hill, USA)

The generalized Kummer variety $K_n$ of an abelian surface $A$ is the fibre of the natural map $\mathsf{Hilb}^{n+1}A\to \mathsf{Sym}^{n+1}A\to A$. Debarre described a Lagrangian fibration on $K_n$ whose fibres are the kernels of $\mathsf{Jac}C\to…

Chaos maps and study of the Geminids meteor shower – Ariane Courtot (Observatoire de Paris)

Meteor showers originate from a parent body, an asteroid or a comet. This parent body ejects several meteroids, forming a meteoroid stream, which will then meet the Earth. From Earth, several meteors can then be observed. To prove they form a shower, we then need to prove whether they come from the same source.…
