Consider a matrix $A$ with complex, bounded, coefficients, which satisfies an ellipticity condition. In 1953 Tosio Kato asked what is…

Pattern reconstruction with restricted Boltzmann machines – Giuseppe Genovese (University of Zurich)
A Restricted Boltzmann machine (RBM) is a Gibbs probability distribution of great theoretical and methodological relevance in machine learning. It…
Acyclicity in bounded cohomology – Marco Moraschini (Università di Bologna)
Bounded cohomology is an invariant of groups introduced by Johnson in the 70s and then extensively studied both in geometric…
Many interacting particles and their effective theories: the case of Fermions in the mean-field and semiclassical regimes – Chiara Saffirio (University of Basel)
The derivation of effective macroscopic theories approximating microscopic systems of interacting particles in some scaling limit is a major question…
A geometric approach to deriving and numerically integrating models with transport-type noise in geophysical fluid dynamics – Erwin Luesink (University of Twente)
In this talk I will discuss how the framework of geometric continuum mechanics can be made stochastic by introducing the…
(Real) Algebraic Geometry over ℚ – Enrico Savi (Università di Trento)
In this seminar I will present some notions of algebraic geometry over subfields introduced and studied in depth in a…
Calculus of Variations & Geometric Measure Theory
The meeting will be the opportunity to celebrate the 60th birthday of Luigi Ambrosio Speakers:Giovanni Alberti (Università di Pisa)Andrea Braides…
Some results on a simple model of kinetic theory – Federico Bonetto (Georgia Institute of Technology)
In 1955 Mark Kac introduced a simplified model for the evolution of a gas of hard spheres undergoing elastic collisions.…
Hodge-to-singular correspondence – Mirko Mauri (IST Austria)
We show that the cohomology of moduli spaces of Higgs bundles decomposes in elementary summands depending on the topology of the symplectic singularities on a (fixed!) master object and/or the combinatorics of certain posets and lattice polytopes.…
(Non-archimedean) SYZ fibrations for Calabi-Yau hypersurfaces – Enrica Mazzon (University of Regensburg)
The SYZ conjecture is a conjectural geometric explanation of mirror symmetry. Based on this, Kontsevich and Soibelman proposed a non-archimedean approach, which led to the construction of non-archimedean SYZ fibrations by Nicaise-Xu-Yu. A recent…
