AVVISO DI SEMINARIO
Giovedì, 12 ottobre 2023, alle ore 14:30, in Aula G, la Professoressa Silvia Barbina dell’Università degli Studi di Camerino (MC) terrà un seminario dal titolo
Abstract: A Steiner triple system (STS) is a set S together with a collection B of subsets of S of size 3 such that any two elements of S belong to exactly one element of B. Recently, the infinite counterparts of these structures have proven interesting from a model theoretic viewpoint. We will survey recent results in the area, and introduce current work on free constructions of Steiner systems

NIPn fields
Abstract:
NIPn theories are a direct generalization of NIP theories, and their behavior is erratic: classical theorems on NIP theories can often be generalized to arbitrary n, but when they can't, they usually fail spectacularly. Structures which are strictly NIPn are known to exist, however, all NIPn fields seem to be NIP. In this talk, we will present several recent results on NIPn henselian valued fields, most notably, that a henselian valued field of residue characteristic p is NIPn if and only if it is NIPn as a pure field.

“Geometry of the unit sphere in polynomial spaces and applications”
Abstract
We shall present a brief (although global) perspective on the geometry of spaces of polynomials. More particularly, we will focus on polynomial spaces of dimension 3, providing, in that case, a graphical representation of the unit ball. Also, the extreme points in the unit ball of several polynomial spaces are characterized. A number of applications to obtain sharp classical polynomial inequalities will be presented as well.
This work is partly based on the recent research monograph [1], which is the first ever complete account on the geometry of the unit ball of polynomial spaces. Nowadays there are many research papers on this topic and this work gathers the state of the art of the main and/or relevant results up to now, some of which were originally started by authors such as R. M. Aron, Y. S. Choi, or M. Klimek, among others. We shall also comment on some new results from several ongoing joint works with M. Han, E. D’Aniello, S.K. Kim, M. Maiuriello, and G.A. Muñoz ([2,3]).

A model-theoretic approach to the Gamma function and Riemann zeta function
Abstract: O-minimality is an area of mathematical logic with important applications to analysis, number theory, and functional transcendence. In this talk, I will discuss joint work with P. Speissegger in which we prove two classes of functions are o-minimal on certain kinds of domains in the complex numbers. This work allows tools from o-minimality to be used to study the Gamma function and Riemann zeta function.

Noetherianity and equationality
Abstract: A theory is noetherian if there is a family of definable sets with the descending chain condition such that every definable set is a boolean combination of those in the family. Noetherianity captures some of the desired properties of algebraically closed fields in any characteristic or differentially closed fields in characteristic 0. Noetherian theories are in particular omega-stable and equational. In recent work with M. Ziegler, we have shown that the theory of proper pairs of algebraically closed fields in any characteristic is noetherian.

Definable henselian valuations in positive residue characteristic
Abstract: Valuations arise as non-archimedean generalizations of absolute values, with examples coming from all over number theory and algebraic geometry. In many cases, henselian valuations turn out to be definable in the language of rings, a phenomenon famously observed (although perhaps not in these terms) by Julia Robinson in the context of the p-adics. In the late 2010s, Jahnke and Koenigsmann started a classification of when a henselian valuation is definable on a henselian field, providing a full characterization for the case where the so-called canonical henselian valuation has residue characteristic zero. We extend their work to the case where the residue characteristic is positive, drawing on the toolkit of independent defect to summon a definable henselian valuation out of certain defect extensions. This is joint work with Margarete Ketelsen (Münster) and Piotr Szewczyk (Dresden).

“Torus-like solutions for the Landau de Gennes model”
Abstract
We report on some recent progress (in collaboration with F. Dipasquale and V.Millot) about the study of global minimizers of a continuum Landau-De Gennes energy functional for nematic liquid crystals in three-dimensional domains. First, we discuss absence of singularities for minimizing configurations under norm constraint, as well as absence of the isotropic phase for the unconstrained minimizers, together with the related biaxial escape phenomenon. Then, under suitable assumptions on the topology of the domain and on the Dirichlet boundary condition, we show that smoothness of energy minimizing configurations yields the emergence of nontrivial topological structure in their biaxiality level sets. Then, we discuss the previous properties under both the norm constraint and an axial symmetry constraint, showing that in this case only partial regularity is available, away from a finite set located on the symmetry axis. In addition, we show that singularities may appear due to energy efficiency and we describe precisely the asymptotic profile around singular points. Finally, in an appropriate class of domains and boundary data we obtain qualitative properties of the biaxial surfaces, showing that smooth minimizers exibit torus structure, as predicted in numerical simulations.

AVVISO DI SEMINARIO
Mercoledì 29 maggio 2024, alle ore 12:00, nella saletta seminari, il Professore Riccardo Aragona (Dipartimento di Ingegneria e Scienze dell'Informazione e Matematica, Università dell'Aquila) terrà un seminario dal titolo
Abstract:
In crittografia simmetrica, le funzioni di round utilizzate come elementi costitutivi nei cifrari a blocchi iterati sono ottenute come composizione di una sequenze di differenti trasformazioni biunivoche che forniscono una complessità globale crescente. Lo studio delle condizioni su tali trasformazioni che rendono il gruppo generato dalle funzioni di round di un cifrario a blocchi un gruppo primitivo è stato affrontato negli ultimi anni, sia nel caso dei Substitution Permutation Network sia nel caso dei Feistel Network. In particolare, questi risultati forniscono ai progettisti di cifrari a blocchi la ricetta per evitare l'attacco di imprimitività, che sfrutta l'invarianza di alcuni sottospazi durante la cifratura. Nel caso degli schemi Lai-Massey, dove sono combinate sia le caratteristiche del Substitution Permutation Network che quelle del Feistel Network, la resistenza contro gli attacchi di imprimitività è stato per molto tempo un problema aperto. In questo talk consideriamo una generalizzazione di tale schema e dimostriamo la sua resistenza contro l'attacco di imprimitività. Il nostro risultato è ottenuto come conseguenza di un teorema più generale in cui il problema di dimostrare la primitività di uno schema Lai–Massey generalizzato si riduce a quello più semplice di dimostrare la primitività del gruppo generato dalle funzioni di round di un Substitution Permutation Network strettamente collegato a tale schema.

“Exploring hypercyclic and supercyclic behaviors of composition operators”
Abstract
We investigate chaotic notions (like hypercyclicity, frequent hypercyclicity and supercyclicity) in the context of composition operators on Lp, 1 ≤p <∞. Moreover, motivated by recent investigations on the notion of recurrence in Linear Dynamics, we deepen into a parallelism between the notions of (frequent) hypercyclicity and (frequent) recurrence in the setting of dissipative composition operators with bounded distortion, a class of linear operators which includes weighted backward shifts.
