Analytical solution of space-time fractional telegraph-type equations involving Hilfer and Hadamard derivatives

In this paper we consider space-time fractional telegraph equations, where the time derivatives are intended in the sense of Hilfer and Hadamard while the space-fractional derivatives are meant in the sense of Riesz-Feller. We provide the Fourier transforms of the solutions of some Cauchy problems for these fractional equations. Probabilistic interpretations of some specific cases are also provided.     

Estimation of parameters in the fractional compound Poisson process

On the non-differentiable exact solutions of the (2 + 1)-dimensional local fractional breaking soliton equation on Cantor sets

In this article, a new (2 + 1)-dimensional local fractional breaking soliton equation is derived with the local fractional derivative. Applying the traveling wave transform of the non-differentiable type, the (2 + 1)-dimensional local fractional breaking soliton equation is converted into a nonlinear local fractional ordinary differential equation. By defining a set of elementary functions on Cantor sets, a novel analytical technique namely the Mittag–Leffler function-based method is employed for the first time ever to construct the exact solutions. The solutions on the Cantor sets are presented via the 3-D contours. It reveals that the proposed method is effective and powerful and is expected to give some inspiration for the study of the local fractional PDEs.     

Controllability Results for Fractional Functional Differential Equations with Nondense Domain

This article is concerned with the controllability results for integral solution of nondensely defined fractional semilinear functional differential equations. Our approach is based on integrated semigroup theory and the Schauder fixed point theorem. An example is also given to illustrate our results.

Random Dynamical Systems and Stationary Solutions of Differential Equations Driven by the Fractional Brownian Motion

Abstract

Linear and semilinear stochastic evolution equations with additive noise, where the forcing term is an infinite dimensional fractional Brownian motion are studied. Under usual dissipativity conditions the equations are shown to define random dynamical systems which have unique, exponentially attracting fixed points. The results are applied to stochastic parabolic PDE's. They are also applicable to standard finite-dimensional dissipative stochastic equation driven by fractional Brownian motion.

Series Solutions of Systems of Nonlinear Fractional Differential Equations

Differential equations of fractional order appear in many applications in physics, chemistry and engineering. An effective and easy-to-use method for solving such equations is needed. In this paper, series solutions of the FDEs are presented using the homotopy analysis method (HAM). The HAM provides a convenient way of controlling the convergence region and rate of the series solution. It is confirmed that the HAM series solutions contain the Adomian decomposition method (ADM) solution as special cases.      

Fractional Intertwinings Between Two Markov Semigroups

We define the notion of α-intertwining between two Markov Feller semigroups on and we give some examples. The 1-intertwining, in particular, is merely the intertwining via the first derivative operator. It can be used in the study of the existence of pseudo-inverses, a notion recently introduced by Madan et al. (2008) and Roynette and Yor (2008).
