Before stating our main result we present the stochastic scenario which underlies the dynamics given by fractional material derivative. Then we introduce a Levy walk process of distributed-order type to establish our main result, which is the scaling limit of the considered process. It appears that the probability density function of the scaling limit process fulfills, in a weak sense, the fractional diffusion equation with material derivative of distributed-order type.", "revisions": [ { "version": "v1", "updated": "2015-10-01T16:57:59.000Z" } ], "analyses": { "subjects": [ "34A08", "26A33", "60F17", "60G50", "60G51", "60B05", "60J75" ], "keywords": [ "fractional diffusion equation", "stochastic foundations", "distributed-order material derivative", "fractional material derivative", "main result" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
