Fractional Brownian motions ruled by nonlinear equations
Roberto Garra, Elena Issoglio, Giorgio S. Taverna
In this note we consider generalized diffusion equations in which the diffusivity coefficient is not necessarily constant in time, but instead it solves a nonlinear fractional diff…
Modeling biological systems with an improved fractional Gompertz law
Luigi Frunzo, Roberto Garra, Andrea Giusti +1
The aim of this paper is to provide a fractional generalization of the Gompertz law via a Caputo-like definition of fractional derivative of a function with respect to another func…
Scott-Blair models with time-varying viscosity
Ivano Colombaro, Roberto Garra, Andrea Giusti +1
In a recent paper, Zhou et al. [Mech Time-Depend Mater (2017) 21: 151] studied the time-dependent properties of Glass Fiber Reinforced Polymers composites by employing a new rheolo…
On Scott-Blair model with time-varying viscosity in linear viscoelasticity
Roberto Garra, Francesco Mainardi
In a recent paper, Zhou et al. studied the time-dependent properties of Glass Fiber Reinforced Polymers (GFRP) composites by using a new rheological model with a time-variable visc…
