Transport of magnetic bright points on the Sun. Analys is of subdiffusion scenarios

In this paper we compare two types of subdiffusion applied to random motion of magnetic bright points at the solar photosphere. One is due to the inverse-time alpha -stable Levy process as a subordinator, another is subordinated by the alpha -stable process. The recommendation to identify each type...

Description
Summary:In this paper we compare two types of subdiffusion applied to random motion of magnetic bright points at the solar photosphere. One is due to the inverse-time alpha -stable Levy process as a subordinator, another is subordinated by the alpha -stable process. The recommendation to identify each type of subdiffusion in the solar experiment is suggested. The difference of these scenarios lies in distinct contrast to the description with the corresponding subdiffusive fractional Fokker-Planck approach, thus providing experimentalists an test to differentiate between the two subdiffusion scenarios.
