Hypergraphx-data: a repository for higher-order network data
Quintino Francesco Lotito, Lorenzo Betti, Berné Nortier +2
The availability of network datasets advances research in network science, machine learning and related fields by enabling empirical analyses and their reproducibility, algorithm d…
Information theory for hypergraph similarity
Helcio Felippe, Alec Kirkley, Federico Battiston
Comparing networks is essential for a number of downstream tasks, from clustering to anomaly detection. Despite higher-order interactions being critical for understanding the dynam…
Collective dynamics on higher-order networks
Federico Battiston, Christian Bick, Maxime Lucas +3
Higher-order interactions that nonlinearly couple more than two nodes are important in many networked systems, and their effects on collective dynamics are increasingly being studi…
STAFF: Stateful Taint-Assisted Full-system Firmware Fuzzing
Alessio Izzillo, Riccardo Lazzeretti, Emilio Coppa
Modern embedded Linux devices, such as routers, IP cameras, and IoT gateways, rely on complex software stacks where numerous daemons interact to provide services. Testing these dev…
Independence Axioms in Social Ranking
Takahiro Suzuki, Michele Aleandri, Stefano Moretti
Independence from non-essential changes in input information is a widely recognized axiom in social choice theory. This independence reduces the cost of specifying and/or analyzing…
Mill's canons meet social ranking: A characterization of plurality
Takahiro Suzuki, Michele Aleandri, Stefano Moretti
In his book entitled ''A System of Logic, Ratiocinative and Inductive'' (1843), John Stuart Mill proposed principles of inductive reasoning in the form of five canons. To date, the…
Hierarchical Random Measures without Tables
Marta Catalano, Claudio Del Sole
The hierarchical Dirichlet process is the cornerstone of Bayesian nonparametric multilevel models. Its generative model can be described through a set of latent variables, commonly…
Ranking alternatives from opinions on criteria
Takahiro Suzuki, Stefano Moretti, Michele Aleandri
A primary challenge in collective decision-making is that achieving unanimous agreement is difficult, even at the level of criteria. The history of social choice theory illustrates…
Existence of Viscosity Solutions to Abstract Cauchy Problems via Nonlinear Semigroups
Fabian Fuchs, Max Nendel
In this work, we provide conditions for nonlinear monotone semigroups on locally convex vector lattices to give rise to a generalized notion of viscosity solutions to a related non…
Emission impossible: Balancing Environmental Concerns and Inflation
René Aïd, Maria Arduca, Sara Biagini +1
We provide a theoretical framework to examine how carbon pricing policies influence inflation and to estimate the policy-driven impact on goods prices from achieving net-zero emiss…
Lecture Notes in Loop Quantum Gravity. LN2: Cauchy problems and pre-quantum states
S. Coriasco, L. Fatibene, S. Garruto +1
We discuss the structure of covariant equations, relating analytical properties of solutions to algebraic properties of the corresponding differential operator, specifically of its…
Consistent Tie-Strength Labeling for Multilayer Strong Triadic Closure
Lutz Oettershagen, Athanasios L. Konstantinidis, Fariba Ranjbar +1
Inferring tie strengths (strong vs. weak) is a core task in network analysis, often guided by the Strong Triadic Closure (STC) principle. In multilayer networks, such as social pla…
Games played by Exponential Weights Algorithms
Maurizio d'Andrea, Fabien Gensbittel, Jérôme Renault
This paper studies the last-iterate convergence properties of the exponential weights algorithm with constant learning rates. We consider a repeated interaction in discrete time, w…
Leveraging Content Producer Networks and User Perception to Detect Online Discursive Communities
Stefano Guarino, Ayoub Mounim, Guido Caldarelli +1
Online discussions are often characterized by strong behavioral asymmetries: a relatively small fraction of users actively produces content, while the majority primarily consumes a…
Global solutions to quadratic systems of stochastic reaction-diffusion equations in space-dimension two
Marta Leocata, Julien Vovelle
We prove the existence of global-in-time regular solutions to a system of stochastic quadratic reaction-diffusion equations. Global-in-time existence is based on a -estim…
Introduction to Loop Quantum Gravity. The Holst's action and the covariant formalism
L. Fatibene, A. Orizzonte, A. Albano +4
We review Holst formalism and we discuss dynamical equivalence with standard GR (in dimension 4). Holst formalism is written for a spin coframe field and a -conn…
Stochastic optimal control in Hilbert spaces: regularity of the value function and optimal synthesis via viscosity solutions
Filippo de Feo, Andrzej Święch, Lukas Wessels
We study optimal control problems governed by abstract infinite dimensional stochastic differential equations using the dynamic programming approach. In the first part, we prove Li…
Monotonicity of Equilibria in Nonatomic Congestion Games
Roberto Cominetti, Valerio Dose, Marco Scarsini
This paper studies the monotonicity of equilibrium costs and equilibrium loads in nonatomic congestion games, in response to variations of the demands. The main goal is to identify…
Phase Transitions of the Price-of-Anarchy Function in Multi-Commodity Routing Games
Roberto Cominetti, Valerio Dose, Marco Scarsini
We consider the behavior of the price of anarchy and equilibrium flows in nonatomic multi-commodity routing games as a function of the traffic demand. We analyze their smoothness w…
Understanding the householder solar panel consumer: A Markovian model and its societal implications
Marta Leocata, Giulia Livieri, Silvia Morlacchi +3
Household adoption of rooftop photovoltaic (PV) systems is central to the green energy transition, yet diffusion depends on social influence and behavioral biases, as well as payba…
Minimal H-factors and covers
Lorenzo Federico, Joel Larsson Danielsson
Given a fixed small graph H and a larger graph G, an H-factor is a collection of vertex-disjoint subgraphs , each isomorphic to H, that cover the vertices of G. If G i…
Structural properties in the diffusion of the solar photovoltaic in Italy: individual people/householder vs firms
Franco Flandoli, Fausto Corvino, Marta Leocata +3
This paper develops two mathematical models to understand subjects' behavior in response to the urgency of a change and inputs from governments e.g., (subsides) in the context of t…
Unit Averaging for Heterogeneous Panels
Christian Brownlees, Vladislav Morozov
In this work we introduce a unit averaging procedure to efficiently recover unit-specific parameters in a heterogeneous panel model. The procedure consists in estimating the parame…
Identifying maximal sets of significantly interacting nodes in higher-order networks
Lorenzo Betti, Federico Musciotto, Federico Battiston +1
Filtering methods are fundamental tools for extracting the backbone of complex networks. Systems displaying group interactions, however, open the way to new types of filtering appr…
