Some new necessary and sufficient conditions for the existence of analytic resolving families operators to linear equation with a distributed Riemann–Liouville derivative in Banach space are established. We study unique solvability natural initial value problem fractional derivatives corresponding inhomogeneous equations. These abstract results applied class boundary problems equations time pol...
this paper is devoted to the study of establishing sufficient conditions forexistence and uniqueness of positive solution to a class ofnon-linear problems of fractional differential equations. the boundary conditionsinvolved riemann-liouville fractional order derivative and integral. further, the non-linear function $f$ containfractional order derivative which produce extra complexity. thank to...
The fractional massive Thirring model is a coupled system of nonlinear PDEs emerging in the study complex ultrashort pulse propagation analysis wave functions. This article considers NFMT terms modified Riemann–Liouville derivative. novel travelling solutions considered are investigated by employing an effective analytic approach based on transformation and Jacobi elliptic extended function met...
The theory of derivatives and integrals of non-integer order goes back to Leibniz, Liouville, Grunwald, Letnikov and Riemann. The history of fractional vector calculus (FVC) has only 10 years. The main approaches to formulate a FVC, which are used in the physics during the past few years, will be briefly described in this paper. We solve some problems of consistent formulations of FVC by using ...
Comparative Study on Solving Fractional Differential Equations via Shifted Jacobi Collocation Method
In this paper, operational matrices of Riemann-Liouville fractional integration and Caputo fractional differentiation for shifted Jacobi polynomials are considered. Using the given initial conditions, we transform the fractional differential equation (FDE) into a modified fractional differential equation with zero initial conditions. Next, all the existing functions in modified differential equ...
This article is in continuation of the authors research attempts to derive computational solutions of an unified reaction-diffusion equation of distributed order associated with Caputo derivatives as the time-derivative and Riesz-Feller derivative as space derivative. This article presents computational solutions of distributed order fractional reaction-diffusion equations associated with Riema...
The authors shall discuss Heinz inequalities involving Riemann-Liouville fractional integrals for certain unitarily invariant norms. By using the convexity of function and fractional Hermit-Hadamard integral inequality, some refinements of Heinz inequalities are derived.
