How network properties and epidemic parameters influence stochastic SIR dynamics on scale-free random networks
Sara Sottile, Ozan Kahramanoğulları, Mattia Sensi
With the premise that social interactions are described by power-law distributions, we study a SIR stochastic dynamic on a static scale-free random network generated via configurat…
A geometric analysis of the SIRS epidemiological model on a homogeneous network
Hildeberto Jardón-Kojakhmetov, Christian Kuehn, Andrea Pugliese +1
We study a fast-slow version of an SIRS epidemiological model on homogeneous graphs, obtained through the application of the moment closure method. We use GSPT to study the model,…
Evolutionary dynamics in an SI epidemic model with phenotype-structured susceptible compartment
Tommaso Lorenzi, Andrea Pugliese, Mattia Sensi +1
We present an SI epidemic model whereby a continuous variable captures variability in proliferative potential and resistance to infection among susceptibles. The occurrence of heri…
Exact solutions for a Solow-Swan model with non-constant returns to scale
Nicolò Cangiotti, Mattia Sensi
The Solow-Swan model is shortly reviewed from a mathematical point of view. By considering non-constant returns to scale, we obtain a general solution strategy. We then compute the…
Notes on a conformal characterization of -dimensional Lorentzian manifolds with constant Ricci scalar curvature
Nicolò Cangiotti, Mattia Sensi
We present a characterization of -dimensional Lorentzian manifolds with constant Ricci scalar curvature. It is well known that every -dimensional Lorentzian manifolds is conf…
A geometric characterization of VES and Kadiyala-type production functions
Nicolò Cangiotti, Mattia Sensi
The basic concepts of the differential geometry are shortly reviewed and applied to the study of VES production function in the spirit of the works of Vîlcu and collaborators. A si…
A geometric analysis of the SIR, SIRS and SIRWS epidemiological models
Hildeberto Jardón-Kojakhmetov, Christian Kuehn, Andrea Pugliese +1
We study fast-slow versions of the SIR, SIRS, and SIRWS epidemiological models. The multiple time scale behavior is introduced to account for large differences between some of the…
