Introduction and Preliminaries
The q-calculus is not of recent appearance, it was introduced in the twenties of last century. In 1910, Jackson [1] introduced and developed q-calculus systematically. The fractional q-calculus is the expansion of ordinary fractional calculus in the q-theory. Recently, there was a significant work done by many authors in the area of q-calculus due to lots of applications in mathematics, statistics, and physics.
Since special functions play significant roles in mathematical physics, it is persuaded to think that some deformation of the ordinary special functions based on the q-calculus can also play comparable roles in this area of research. Further, many authors have derived images of various q-special functions under fractional q-calculus operators; see, for example, [2][3][4][5][6][7], and may more. The q-fractional integrals and derivatives was firstly studied by Al-Salam [8] (see also, [9]). Many researchers have used these operators to evaluate fractional q-calculus formulas for various special function, general class of q-polynomials, basic analogue of Fox's H-function, fractional q-calculus formulas for various special function, and etc. One may refer to the recent work [2][3][4][5][6][7][10][11][12][13][14] on fractional q-calculus. Throughout this article, let ℤ, ℂ, ℝ, ℝ + , and N be the sets of integers, complex numbers, real numbers, positive real numbers, and positive integers, respectively, and let.
The objective of this article is to establish fractional q-integral and q-derivative of Riemann-Liouville type involving a basic analogue of multivariable H-function. We also give an application of q-Leibniz formula.
In the q-calculus theory, for a real parameter q ∈ ℝ + \ f1g, we have a q-real number ½aq and q-shifted factorial (q-analogue of the Pochhammer symbol) as given by The q-Factorial function is defined by Its extension is which can be elaborated to n = α ∈ ℂ, given by where the principal value of q α is taken.
In terms of the q-gamma function, (2) can be written as where the q-gamma function [15] is given by obviously, The q-analogue of the familiar Riemann-Liouville fractional integral operator of a function f ðxÞis defined by (see Al-Salam [8]) also q-analogue of the power function is defined as The basic integral is given by (see Gasper and Rahman [15]) The equation (8) in conjunction with (10) yield the following series representation of the Riemann-Liouville fractional integral operator In particular, for f ðxÞ = x λ−1 , we have [4]

Basic Analogue of Multivariable H-Function
In this section, we introduce the basic analogue of multivariable H-function [16,17], given by the following manner: H z 1 , z r ; q ð Þ= H 0,n:m 1 ,n 1 ;⋯;m r ,n r p,q′:p 1 q 1 ;⋯;p r ,q r Journal of Function Spaces , and The integers n, p, q, The poles of integrand are assumed to be simple. The then the basic analogue of multivariable H-function reduces in basic analogue of multivariable Meijer's G-function defined by Khadia and Goyal [18], we obtain where i = 1, ⋯, r; the integers n, p, q, m i , n i , p i , q i are constrained by the inequalities G z 1 ,⋯,z r ; q ð Þ= G 0,n:m 1 ,n 1 ;⋯;m r ,n r p,q′:p 1 q 1 ;⋯;p r ,q r 3 Journal of Function Spaces those of Gðq 1−c ðiÞ j +s i Þði = 1,⋯,n i ÞGðq 1−a j +∑ r i=1 s i Þðj = 1,⋯,nÞ. For large values of js i j, the integrals converge if Rðs log ðz i Þ − log sin πs i Þ < 0ði = 1,⋯,rÞ.

Main Results
In this section, we establish two fractional q-integral formulas about the basic analogue of multivariable H-function. Let U = m 1 , n 1 ; ⋯ ; m r , n r ; V = p 1 , q 1 ; ⋯ ; p r , q r ; Theorem 1. Let RðμÞ > 0, jqj < 1, the Riemann-Liouville fractional q-integral of a product of two basic functions exists, and we have where p i ∈ ℕ, Rðs log ðz i Þ − log sin πs i Þ < 0 for i = 1, ⋯, r.
Proof. To prove the result (19), we consider the left hand side of equation (19) (say I) and take the definitions (8) and (13) into account, we have Interchanging the order of integrations which is permissible under the given conditions, we obtain The above equation writes Now using the result (12), then the equation (22) reduces as Next, interpreting the q-Mellin-Barnes multiple integrals contour in terms of the basic analogue of multivariable H-function, then we get the desired result (19).
If we replace μ by −μ in Theorem 1, and use the fractional qderivative operator defined as and power function formula then we have the following result: where ρ i ∈ ℕ, Rðs log ðz i Þ − log sin πs i Þ < 0 for i = 1, ⋯, r.
Proof. The proof of result asserted by Theorem 2 runs parallel to that of Theorem 1. The details are, therefore, being omitted.

Leibniz's Application
In this section, we give an application concerning the basic analogue of multivariable H-function and q-extension of the Leibniz rule for the fractional q-derivative for a product of two basic functions. We have the q-extension of the Leibniz rule for the fractional q-derivatives for a product of two basic functions in terms of a series involving the fractional q-derivatives of the function, in the following manner [9]: where WðxÞ and YðxÞ are two regular functions.

Theorem 4.
Let RðμÞ < 0,, then the Riemann-Liouville fractional q-derivative of a product of two basic function exists and given by where p i ∈ ℕ, Rðs log ðz i Þ − log sin πs i Þ < 0 for i = 1, ⋯, r.
Proof. For applying q-Leibniz rule, we let By using the lemma 3, we have Next, by setting λ = 1 and using the Theorem 2, we arrive at 5 Journal of Function Spaces where ρ i ∈ ℕ, Rðs log ðz i Þ − log sin πs i Þ < 0ði = 1,⋯,rÞ.
Now, by using (25) and (31) we obtain the desired result (28) after several algebraic manipulations.

Particular Case
In this section, the basic analogue of multivariable H-function reduces in basic analogue of multivariable Meijer's G -function [18]. Let U = m 1 , n 1 ; ⋯ ; m r , n r ; V = p 1 , q 1 ; ⋯ ; p r , q r ; Corollary 5.
Remark 6. If the basic analogue of multivariable H-function reduces in basic analogue of Srivastava-Daout function [19], then we obtain the results given by Purohit et al. [20].
Remark 7. If the basic analogue of multivariable H-function reduces in basic analogue of H-function of two variables defined by Saxena et al. [21], we obtain the result due to Yadav et al. [7]. Further, if the basic analogue of multivariable H-function reduces in basic analogue of H-function of one variable defined by Saxena et al. [22], then we can easily obtain the similar result.

Conclusion
In the present article, we have proposed the fractional order q -integrals and q-derivatives involving a basic analogue of multivariable H-function. The significance of our derived results lies in their diverse generality. By specializing the various parameters as well as variables in the basic analogue of multivariable H-function, we can obtain a large number of results involving a remarkably wide range of useful basic functions (or product of such basic functions) of one and several variables. Hence, the derived formulas in this article are most general in character and may reaffirm to be useful in several interesting cases appearing in literature.
