A fractional approach to study the pure-temporal Epidemic Type Aftershock Sequence (ETAS) process for earthquakes modeling
Lorenzo Cristofaro, Roberto Garra, Enrico Scalas +1
In statistical seismology, the Epidemic Type Aftershocks Sequence (ETAS) model is a branching process used world-wide to forecast earthquake intensity rates and reproduce many stat…
On G-fractional diffusion models in bounded domains
L. Angelani, R. Garra
In the recent literature, the g-subdiffusion equation involving Caputo fractional derivatives with respect to another function has been studied in relation to anomalous diffusions…
The tempered space-fractional Cattaneo equation
Luisa Beghin, Roberto Garra, Francesco Mainardi +1
We consider the time-fractional Cattaneo equation involving the tempered Caputo space-fractional derivative. We find the characteristic function of the related process and we expla…
A note on a modified fractional Maxwell model
Roberto Garra, Armando Consiglio, Francesco Mainardi
In this paper we consider a modified fractional Maxwell model based on the application of Hadamard-type fractional derivatives. The model is physically motivated by the fact that w…
