It is well known (is it?) that many dynamical systems arising from physical or chemical models exhibit what is probably…

The degree of Kummer extensions of number fields – Flavio Perissinotto (University of Luxembourg)
Under the Generalized Riemann Hypothesis, densities of prime ideals of a number field $K$ for which a given subgroup $G$…
Weekend di lavoro su Calcolo delle Variazioni
Further information is available on the event page on the Indico platform.…
P=W via $H_2$ – Anton Mellit (University of Vienna)
By $H_2$ we denote the Lie algebra of polynomial hamiltonian vector fields on the plane. We consider the moduli space of stable twisted Higgs bundles on an algebraic curve of a given coprime rank and degree. De Cataldo, Hausel and Migliorini proved…
Definisci il tuo futuro – Incontro con la società di consulenza d-fine – Matthias Blank, Carla Mereu (d-fine)
Tutti abbiamo bisogno di un lavoro, ma di cosa ha bisogno la mente di un matematico? A d-fine lo sappiamo…
Quot schemes and their d-critical structure(s) – Andrea Ricolfi (SISSA, Trieste)
D-critical schemes and Artin stacks were introduced by Joyce in 2015, and play a central role in Donaldson-Thomas theory. They typically occur as truncations of (-1)-shifted symplectic derived schemes, but the problem of constructing the d-critical…
Metric theory of the weighted products of partial quotients in continued fractions – Ayreena Bakhtawar (Centro De Giorgi – SNS)
The fundamental objective of the theory of Diophantine approximation is to seek an answer to a simple question “how well irrational numbers can be approximated by rational numbers?” In this regard the theory of continued fractions provides a quick…
Old and new questions in the regularity theory of the d-bar-Neumann problem – Gian Maria Dall'Ara (Scuola Normale Superiore di Pisa)
In this talk, I will discuss various questions in the analysis of the d-bar-Neumann problem, a classical noncoercive boundary value…
The dependence of the psc space of a manifold from its normal 2-type – Agnese Mantione (University of Münster)
Gromov and Lawson’s surgery theorem states that positive scalar curvature (psc) is invariant under surgeries of codimension at least 3.…
Baxter Q-operators, QQ-systems and the shifted Yangian – Rouven Frassek (Università di Modena e Reggio Emilia)
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…
