Application of the fractional conservation of mass to Gas Flow diffusivity equation in heterogeneous porous media
A. Caserta, R. Garra, E. Salusti
In this paper we reconsider the classical nonlinear diffusivity equation of real gas in an heterogenous porous medium in light of the recent studies about the generalized fractiona…
Random motions with space-varying velocities
R. Garra, E. Orsingher
Random motions on the line and on the plane with space-varying velocities are considered and analyzed in this paper. On the line we investigate symmetric and asymmetric telegraph p…
Nonlinear heat conduction equations with memory: physical meaning and analytical results
Pietro Artale Harris, Roberto Garra
We study nonlinear heat conduction equations with memory effects within the framework of the fractional calculus approach to the generalized Maxwell-Cattaneo law. Our main aim is t…
Some probabilistic properties of fractional point processes
R. Garra, E. Orsingher, M. Scavino
This paper studies the first hitting times of generalized Poisson processes , related to Bernstein functions . For the space-fractional Poisson processes, , $t>0…
Confinement of a hot temperature patch in the modified SQG model
Roberto Garra
In this paper we study the time evolution of a temperature patch in according to the modified Surface Quasi-Geostrophic Equation (SQG) patch equation. In particular we give a…
