On a Donaldson functional for CMC-immersions of surfaces into hyperbolic 3-manifolds

We discuss a parametrization for the moduli space of Constant Mean Curvature (CMC)immersions of a closed surface S (orientable and of genus at least 2) into hyperbolic 3-manifolds by elements of the t...

A filtering monotonization technique for DG discretizations of hyperbolic problems

In this talk, I will introduce a filtering technique for Discontinuous Galerkin approximations of hyperbolic problems. After a brief overview of classical monotonization techniques, I will present an ...

Long time asymptotic of action functionals

I will provide a self-contained variational approach to state some classical and new results in the framework of Aubry-Mather theory. More precisely, I will discuss the expansion by Gamma-convergence ...

Large blowup-sets for Q-curvature equations

On a bounded domain of the Euclidean space R2m,m>1, Adimurthi, Robert and Struwe pointed out that, even assuming a volume bound ∫e2mudx≤C, some blow-up solutions for prescribed Q-curvature equation...

Baxter Q-operators, QQ-systems and the shifted Yangian

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 o...

Racconti di carte e di numeri

 Il seminario è stato organizzato dalla Biblioteca di Matematica allo scopo di presentare il lavoro svolto dai due tirocinanti della Facoltà di Lettere e Culture Moderne, Irene Guerriero e France...

Robust Fourier fingerprints for crystals and generalizations

I will start by giving an introductory overview of different notions of generalized crystals (including quasicrystals), unified by the requirement that their Fourier transforms are atomic. Then we stu...

On the metric structure of section rings and holomorphic extension theorem

We study the relationship between metric and algebraic structures on section rings of polarized projective manifolds. More precisely, we prove that once the kernel is factored out, the multiplication ...

Predictive control for non-linear collective dynamics and their mean-field limit

In this talk I will present the synthesis of control laws for interacting agent-based dynamics and their mean-field limit. In particular, a linearization-based approach is used for the computation of ...

Mixing of the Averaging process on graphs

The Averaging process (a.k.a. repeated averages) is a mass redistribution model over the vertex set of a graph. Given a graph G, the process starts with a non-negative mass associated to each vertex. ...
