| Do 23.10.2025 | Margherita Recchia (LUH) | Some ideas about p-adic Hodge theory We will give a naive introduction to some of the main objects that play a role in p-adic Hodge-Tate decomposition such as rigid analytic varieties and étale cohomology groups. We will then give an idea of a way of investigating Hodge symmetry in the p-adic setting. |
| Do 30.10.2025 | Julian Demeio (LUH)
| Hilbert Property for Hilbert modular surfaces Joint work with Damián Gvirtz. We prove the Hilbert Property for all Hilbert Modular surfaces of base level of K3 type. As an application, we obtain a positive answer to the Inverse Galois Problem in some new cases: namely for PSL_(F_{p^2}) for p lying in a union of several arithmetic sequences. |

| Do 13.11.2025 | Ronald Solodov (LUH) | Some Spaces in Non-Archimedean Geometry We will briefly discuss certain spaces that appear in non-Archimedean geometry, namely rigid analytic and adic spaces, and explain how they are related. If time permits, we will also outline the main result of my master’s thesis, which concerns relative compactifications of adic spaces. |
