Abstract: I will give an explicit description of the space of stability conditions of a set of Calabi-Yau-3 triangulated categories labelled by the Painlevé equations. We will see how the Painlevé equations appear in a Riemann-Hilbert problem motivated by the enumerative geometry of Calabi-Yau-3 categories whose solution is related to the study of the monodromy of opers.

Abstract: While it is well known that the moduli space of G-bundles over a smooth projective curve is compact, it is not the case for an arbitrary base variety. This motivated the definition of G-sheaves by Gomez and Sols who proved that their moduli space is a compactification of the moduli space of G-bundles. In this talk I will study the deformation and obstruction theory of these objects when G is either the symplectic or the orthogonal group.

Abstract: This is a longstanding problem. We will expose a complete axiom system, which is also model complete and satisfied by F_p^{alg}((t)). A proof will be sketched. This work is joint with Françoise Delon (Paris) and Arno Fehm (Dresden) and should be considered as in progress.
Days in Logic will take place in Lisbon (FCUL) in January 30 and 31 and in the morning of February 1, 2020.
This biennial meeting aims at bringing together mathematicians, computer scientists and other researchers with interest in Logic.

Abstract: We present an original model for immiscible two-phase mixtures. This model can be interpreted as the generalised gradient flow of the same energy as for the classical degenerate Canh-Hilliard model, but for a different geometry. Our model is shown to dissipate faster. Existence of weak solutions is established based on the convergence of a JKO semi discretization (joint work with Flore Nabet and Daniel Matthes).
