Fractional kinetics in random/complex media

In this chapter, we consider a randomly-scaled Gaussian process and discuss a number of applications to model fractional diffusion. Actually, this approach can be understood as a Gaussian diffusion in a medium characterized by a population of scales. This interpretation supports the idea that fractional diffusion emerges from standard diffusion occurring in a complex medium.BERC 2014-2017 (Basque Government); BCAM Severo Ochoa excellence accreditation SEV-2013-0323 (Spanish Ministry of Economy and Competitiveness MINECO)
