A Modified Groundwater Flow Model Using the Space Time Riemann-Liouville Fractional Derivatives Approximation

open access: yesAbstract and Applied Analysis, 2014
The notion of uncertainty in groundwater hydrology is of great importance as it is known to result in misleading output when neglected or not properly accounted for. In this paper we examine this effect in groundwater flow models.

On nonlocal problem with fractional Riemann-Liouville derivatives for a mixed-type equation

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
The unique solvability is investigated for the problem of equation with partial fractional derivative of Riemann-Liouville and boundary condition that contains the generalized operator of fractional integro-differentiation. The uniqueness theorem for the

Further Extension of Extended Fractional Derivative Operator of Riemann-Liouville

open access: yes, 2017
The main objective of this present paper is to establish the extension of an extended fractional derivative operator by using an extended beta function recently defined by Parmar et al. by considering the Bessel functions in its kernel. Also, we give some results related to the newly defined fractional operator such as Mellin transform and relations to

On the Qualitative Analysis of Solutions of Two Fractional Order Fractional Differential Equations

open access: yesMathematics
In applied sciences, besides the importance of obtaining the analytical solutions of differential equations with constant coefficients, the qualitative analysis of the solutions of such equations is also very important.
