    Get PDF
    We introduce a truncated MM-fractional derivative type for α\alpha-differentiable functions that generalizes four other fractional derivatives types recently introduced by Khalil et al., Katugampola and Sousa et al., the so-called conformable fractional derivative, alternative fractional derivative, generalized alternative fractional derivative and MM-fractional derivative, respectively. We denote this new differential operator by iDMα,β_{i}\mathscr{D}_{M}^{\alpha,\beta }, where the parameter α\alpha, associated with the order of the derivative is such that 00 0 0 and M M is the notation to designate that the function to be derived involves the truncated Mittag-Leffler function with one parameter. The definition of this truncated MM-fractional derivative type satisfies the properties of the integer-order calculus. We also present, the respective fractional integral from which emerges, as a natural consequence, the result, which can be interpreted as an inverse property. Finally, we obtain the analytical solution of the MM-fractional heat equation and present a graphical analysis.Comment: 16 pages, 3 figure

    Extended Riemann-Liouville fractional derivative operator and its applications

    Get PDF
    Many authors have introduced and investigated certain extended fractional derivative operators. The main object of this paper is to give an extension of the Riemann-Liouville fractional derivative operator with the extended Beta function given by Srivastava et al. [22] and investigate its various (potentially) useful and (presumably) new properties and formulas, for example, integral representations, Mellin transforms, generating functions, and the extended fractional derivative formulas for some familiar functions

    A fractional spline collocation method for the fractional order logistic equation

    Get PDF
    We construct a collocation method based on the fractional B-splines to solve a nonlinear differential problem that involves fractional derivative, i.e. the fractional order logistic equation. The use of the fractional B-splines allows us to express the fractional derivative of the approximating function in an analytic form. Thus, the fractional collocation method is easy to implement, accurate and efficient. Several numerical tests illustrate the efficiency of the proposed collocation method.We construct a collocation method based on the fractional B-splines to solve a nonlinear differential problem that involves fractional derivative, i.e. the fractional order logistic equation.

    Distributed-order fractional Cauchy problems on bounded domains

    Get PDF
    In a fractional Cauchy problem, the usual first order time derivative is replaced by a fractional derivative. The fractional derivative models time delays in a diffusion process. The order of the fractional derivative can be distributed over the unit interval, to model a mixture of delay sources. In this paper, we provide explicit strong solutions and stochastic analogues for distributed-order fractional Cauchy problems on bounded domains with Dirichlet boundary conditions. Stochastic solutions are constructed using a non-Markovian time change of a killed Markov process generated by a uniformly elliptic second order space derivative operator.Comment: 29 page
