The aim of a quantum memory is to protect an encoded quantum state against errors for long periods of time.…

Some remarks on the component group of the Sato-Tate group – Victoria Cantoral Farfán (Georg-August-Universität Göttingen)
The famous Sato-Tate conjecture for elliptic curves defined over a number field (without complex multiplication) predicts the equidistribution of Frobenius…
On the classification problem of countable abelian groups – Martino Lupini (Università di Bologna)
I will present the framework of Borel-definable homological algebra, where classical constructions and invariants from homological algebra are enriched with additional information of descriptive set-theoretic nature. I will then explain how this…
The Complexity of Higher Chow Groups – James Lewis (University of Alberta)
Let $X/{\mathbb C}$ be a smooth projective variety. We consider two integral invariants, one of which is the level of the Hodge cohomology algebra $H^*(X,{\mathbb C})$ and the other involving the complexity of the higher Chow groups ${\rm…
Mixing properties of erasing interval maps – Alessandro Della Corte (Università di Camerino)
We study the measurable dynamical properties of the interval map generated by the model-case erasing substitution $\rho$, defined by: $ \rho(00) = empty word$; $\rho(01) = 1$; $\rho(10) = 0$; $\rho(11) = 01$. We prove that, although the map is…
A family of threefolds with remarkable properties (namely: the unreasonable effectiveness of the Schoens) – Antonella Grassi (Università degli Studi di Bologna)
The fiber product of certain rational elliptic surfaces were first studied by Schoen in the 80s to answer questions from string theory. Over the decades the “Schoens” have provided evidence for various conjectures as well as counterexamples to…
Clustering Solutions for a Boundary Yamabe Problem – Sergio Cruz Blanquez (Università degli Studi della Campania)
In this talk we consider a boundary case of the classical Kazdan-Warner problem in dimension greater or equal than four,…
The influence of a strong oscillating magnetic field in an elastic body – Juan Casado Diaz (Universidad de Sevilla)
We study the homogenization of the elastic system submitted to a strong oscillating magnetic field. We prove that oscillations in time or space make increase the effective mass. More generally, oscillations in time and space produce a new term in…

Ergodic results for the stochastic nonlinear damped Schroedinger equation – Margherita Zanella (Politecnico di Milano)
We study the nonlinear stochastic Schrödinger equation with linear damping. We prove the existence of invariant measures in the case…
