Integro-differential diffusion equation for continuous time random walk
Kwok Sau Fa, K. G. Wang
In this paper we present an integro-differential diffusion equation for continuous time random walk that is valid for a generic waiting time probability density function. Using thi…
Tsallis distribution and luminescence decays
Kwok Sau Fa
Usually, the Kohlrausch (stretched exponential) function is employed to fit the luminescence decays. In this work we propose to use the Tsallis distribution as an alternative to de…
Fokker-Planck equation with variable diffusion coefficient in the Stratonovich approach
Kwok Sau Fa
We consider the Langevin equation with multiplicative noise term which depends on time and space. The corresponding Fokker-Planck equation in Stratonovich approach is investigated.…
Scaling dependence on time and distance in nonlinear fractional diffusion equations and possible applications to the water transport in soils
Kwok Sau Fa, E. K. Lenzi
Recently, fractional derivatives have been employed to analyze various systems in engineering, physics, finance and hidrology. For instance, they have been used to investigate anom…
