I plan to discuss the construction of Baxter Q-operators within the framework of the Quantum Inverse Scattering Method. The method follows the standard procedure for the transfer matrix construction of spin chains that was developed by Faddeev and…

Collinearity on cubic surfaces – Jan Dobrowolski (University of Manchester)
We study the ternary relation R of collinearity between points of a smooth cubic surface X. Our aim is to understand sequences of triples (A,B,C) of finite sets with |A|=|B|=|C| whose Cartesian products have asymptotically maximal possible size of…
Estimating the level of noise in time series using entropy methods – Andrea Scarciglia (Università di Pisa)
Identification of underlying noise in time series is essential for applications ranging from physiology to econometrics, with relevance in all…

Normalized solutions for non-autonomous Schroedinger equations in $R^n$ and exterior domains – Riccardo Molle (Università Roma Tor Vergata)
This talk concerns with some recent results about theexistence of positive solutions with prescribed mass for nonlinearSchrödinger equations with a…
A diagram-free approach to the stochastic estimates in regularity structures – Markus Tempelmayr (Max Planck Institute for Mathematics in the Sciences in Leipzig)
We present an alternative point of view on Hairer’s regularity structures that is well suited, but not restricted to, quasilinear…
Recent extensions of scalar and matrix polynomial properties and their interactions – Aaron Melman (Santa Clara University, USA)
Several results for scalar polynomials are extended and then generalized to matrix polynomials. Among them are a directional version of Pellet’s theorem for both scalarand matrix polynomials, which establishes an exclusion interval for the…
Arithmetic of homogeneous spaces over global fields of characteristic p – David Harari (Université de Paris-Saclay)
Let $K$ be the function field of a curve over a finite field. Let $X$ be a homogeneous space of a reductive group over $K$. We discuss cohomological obstructions to the local-global principle on $X$. Similar results for weak and strong approximation…
