Title: " An explicit wall crossing for the moduli space of hyperplane arrangementss"
Abstract:
Given the moduli space of hyperplanes in projective space, V. Alexeev constructed a family of compactifications parametrizing stable
hyperplane arrangements with respect to given weights. In particular, there is a toric compactification that generalizes the Losev–Manin
compactification for the moduli of points on the line. We study the first natural wall crossing that modifies this compactification into
a non-toric one by varying the weights. In particular, we prove that in dimensions two the wall crossing corresponds to blowing up at the
identity of the generalized Losev–Manin space. As an application, we show that any Q-factorialization of this blow-up is not a Mori dream
space for a sufficiently high number of lines. This is joint work in progress with Patricio Gallardo.
This talk is part of the activity of the MIUR Excellence Department Projects MathMod@TOV, and the PRIN 2022 Moduli Spaces and Birational Geometry

Title: " Strong solutions to submodular mean field games with common noise and related McKean-Vlasov FBSDEs "
Speaker: Quentin Berger - Sorbonne Université, Paris
Abstract:
The goal of my talk is to present some results on the Ising model on a Galton-Watson tree. I will start with a general introduction,
recalling in particular the seminal results of Russell Lyons. I will the present the results obtained in collaboration with Irene Ayuso Ventura (University Paris-Est Créteil),
which estimate the effect of a sparse external field or boundary condition on the magnetisation of the root.

Title: " The double semion model in infinite volume "
Speaker: Yasuyuki Kawahigashi - The University of Tokyo
Abstract:
Abstract:
Alpha-induction is a tensor functor producing a new fusion
category from a modular tensor category and a Q-system. This can be
formulated in terms of quantum 6j-symbols and braiding and gives
alpha-induced bi-unitary connections. Last year, we showed that locality of
the Q-system implies flatness of the alpha-induced connections. We now
prove that the converse also holds.
