Coevolutionary dynamics of a variant of the cyclic Lotka-Volterra model with three-agent interactions
Filippo Palombi, Stefano Ferriani, Simona Toti
We study a variant of the cyclic Lotka-Volterra model with three-agent interactions. Inspired by a multiplayer variation of the Rock-Paper-Scissors game, the model describes an ide…
Influence of periodic external fields in multiagent models with language dynamics
Filippo Palombi, Stefano Ferriani, Simona Toti
We investigate large-scale effects induced by external fields, phenomenologically interpreted as mass media, in multiagent models evolving with the microscopic dynamics of the bina…
Topological aspects of the multi-language phases of the Naming Game on community-based networks
Filippo Palombi, Simona Toti
The Naming Game is an agent-based model where individuals communicate to name an initially unnamed object. On a large class of networks continual pairwise interactions lead the sys…
On the Power-Law Tails of Vote Distributions in Proportional Elections
Filippo Palombi, Simona Toti
In proportional elections with open lists the excess of preferences received by candidates with respect to the list average is known to follow a universal lognormal distribution. W…
Use of Dirichlet Distributions and Orthogonal Projection Techniques for the Fluctuation Analysis of Steady-State Multivariate Birth-Death Systems
Filippo Palombi, Simona Toti
Approximate weak solutions of the Fokker-Planck equation can represent a useful tool to analyze the equilibrium fluctuations of birth-death systems, as they provide a quantitative…
Stochastic Dynamics of the Multi-State Voter Model over a Network based on Interacting Cliques and Zealot Candidates
Filippo Palombi, Simona Toti
The stochastic dynamics of the multi-state voter model is investigated on a class of complex networks made of non-overlapping cliques, each hosting a political candidate and intera…
A note on the variance of the square components of a normal multivariate within a Euclidean ball
Filippo Palombi, Simona Toti
We present arguments in favour of the inequalities , where is a normal vector in dimensions, with…
A perturbative approach to the reconstruction of the eigenvalue spectrum of a normal covariance matrix from a spherically truncated counterpart
Filippo Palombi, Simona Toti
In this paper we propose a perturbative method for the reconstruction of the covariance matrix of a multinormal distribution, under the assumption that the only available informati…
Numerical reconstruction of the covariance matrix of a spherically truncated multinormal distribution
Filippo Palombi, Simona Toti, Romina Filippini
In this paper we relate the matrix of the second moments of a spherically truncated normal multivariate to its full covariance matrix and present an algorithm to invert t…
