Also, some of special cases related to fractional calculus operators and -Wright function are considered.

#### 1. Introduction and Preliminaries

Fractional calculus was introduced in 1695, but in the last two decades researchers have been able to use it properly on the account of availability of computational resources. In many areas of application of fractional calculus, the researchers found significant applications in science and engineering. In the literature, many applications of fractional calculus are available in astrophysics, biosignal processing, fluid dynamics, nonlinear control theory, stochastic dynamical system, and so on. Also, a number of researchers [1â€“10] have studied in-depth level of properties, applications, and various directions of extensions of Gauss hypergeometric function of fractional integration.

Recently, in a series of research publications on generalized classical fractional calculus operators, research by Mubeen and Habibullah [11] has been published on the integral part of the Riemann-Liouville version and its applications; an alternative definition for the -Riemannâ€“Liouville fractional derivative was introduced by Dorrego [12]. The left- and right-hand operators of Saigo -fractional integration and differentiation associated with the -Gauss hypergeometric function defined by Gupta and Parihar [13] (see also [14]) are as follows:where is the -Gauss hypergeometric function defined by [11] for :

The corresponding fractional differential operators have their respective forms aswhere , and is the integer part of .

*Remark 1. *If we set in equations (1), (2), (4), and (5), operators reduce to Saigoâ€™s fractional integral and derivative operators stated in [5], respectively.

Now, we consider the following basic results for our study.

Recently, Gehlot and Prajapati [15] studied the concept of the generalized -Wright function, which is presented in the following definition, and its connection with other special functions. It is the generalization of Mittag-Leffler function and many other special functions (see also, [16â€“21]). These special functions have found many important applications in solving problems of physics, biology, engineering, and applied sciences.

The -Wright function is defined for , , and aswith the convergence conditions described as

*Remark 2. *When we put in (10), the -Wright function reduces to Wright function which is stated in [22].

The following relation of the -Wright function in terms of the generalized -Mittag-Leffler function, -Bessel function, -hypergeometric function, and Mittag-Leffler family function is defined as follows by giving the appropriate values of the parameters:(1)For , the generalized -Mittag-Leffler function from Gehlot [17] isâ€‰Here, DĂaz and Pariguan [23] introduced the -Pochhammer symbol and -gamma function as follows:â€‰and the relation with classical Eulerâ€™s gamma function is as follows:â€‰where , and .

In this section, we present the composition formulas of -fractional derivatives (4) and (5), involving the -Wright function.

Theorem 3. *Let , , and such that , . If condition (11) is satisfied and be the left-sided differential operator of the generalized -fractional differentiation associated with -Wright function, then the following equation holds true:*

#### 4. Special Cases and Concluding Remarks

Being very general, the results given in (22), (25), (28), and (31) can yield a wide number of special cases by assigning some appropriate values to the parameters involved. Now, as shown in the following, we are explaining a few corollaries.

Corollary 3. *If we put and in Theorems 1 and 2, then we get the following interesting results on the right known as -Mittag-Leffler function:and*

Corollary 4. *If we put and in Theorems 1 and 2, then we get the following interesting results on the right known as -Bessel function of the first kind:and*

Corollary 5. *If we put and in Theorems 1 and 2, then we get the following results on the right known as -hypergeomrtric function:*

Corollary 6. *If we put and in Theorems 3 and 4, then we get the following results on the right known as -Mittag-Leffler function:*

Corollary 7. *If we put and in Theorems 3 and 4, then we get the following results on the right known as -Bessel function of the first kind:*

Corollary 8. *If we put and in Theorems 3 and 4, then we get the following results on the right known as -hypergeomrtric function:*

The advantage of the generalized -fractional calculus operators, which are also called by many authors as the general operator, is that they generalize Saigoâ€™s fractional calculus operators and classical Riemannâ€“Liouville (R-L) operators. For , operators (1), (2), (4), and (5) reduce to Saigoâ€™s [5] fractional integral and differentiation operators. If we take , (1), (2), (4), and (5) reduce the operators to -Riemannâ€“Liouville as follows:

Due to the most general character of the -Wright function, numerous other interesting special cases from (22), (25), (28), and (31) can be given in the form of -Struve function, -Wright-type function, and many more, but due to lack of space, they are not represented here.
