Comments on Modeling fractional stochastic systems as non-random fractional dynamics driven Brownian motions''.
(English)
[J] Appl. Math. Modelling 33, No. 5, 2534-2537 (2009). ISSN 0307-904X

Summary: Some results presented in the paper Modeling fractional stochastic systems as non-random fractional dynamics driven Brownian motions'' [{\it G. Jumarie} [Appl. Math. Modelling 32, No. 5, 836--859 (2008; Zbl 1138.60324)] are discussed in this paper. The slightly modified Grünwald-Letnikov derivative proposed there is used to deduce some interesting results that are in contradiction with those proposed in the referred paper.
