#### Abstract

Through a modification on the parameters associated with generating function of the -extensions for the Apostol type polynomials of order and level , we obtain some new results related to a unified presentation of the -analog of the generalized Apostol type polynomials of order and level . In addition, we introduce some algebraic and differential properties for the -analog of the generalized Apostol type polynomials of order and level and the relation of these with the -Stirling numbers of the second kind, the generalized -Bernoulli polynomials of level , the generalized -Apostol type Bernoulli polynomials, the generalized -Apostol type Euler polynomials, the generalized -Apostol type Genocchi polynomials of order and level , and the -Bernstein polynomials.

#### 1. Introduction

With the development of -calculus in the mid-19th century, many authors made generalizations to special functions and polynomial families based on the -analogs (cf. [1–7]). During this process, properties and relations have been demonstrated and contributed to solving different kinds of problems in other subjects (see, [8–10]).

In 2003, Natalini P. and Bernardini A. [11] introduced a class the polynomials , considering a class of Appell polynomials defined by using a generating function linked to the Mittag-Leffler function (see, [12, p. 204, Eq. ])Kurt B. [13] did the generalization of the Bernoulli , Euler , and Genocchi polynomials of order and level . Tremblay R. et al. [14, 15] defined the generalized Apostol-Bernoulli polynomials and their properties. In [12] which has studied the unification of Bernoulli, Euler, and Genocchi polynomials they considered the following Mittag-Leffler type function (see, [12, p. 209, Eq. ]):to define a extension of the generalized Apostol type polynomials in , parameters , order , and level through the following generating function:where , , and The numbers were given by Recently a new class of polynomials has been introduced in [16] and it provides a unification of three families of polynomials through the following generating function (see, [16, p. 923, Eq. ]): where , , and . The author named it the unified -Apostol-Bernoulli, Euler, and Genocchi polynomials of order and proved some properties for these unification.

On the other hand, in the definition of the -Mittag-Leffler function when , , and lead us to (see, [17, p. 614, Eq ])which corresponds to the -analog of the generating function defined in (1) and with this, new research emerged about other polynomial families based on the -analogs.

In [18], the authors introduced the generalized -Apostol-Bernoulli polynomials, the generalized -Apostol Euler polynomials, and generalized -Apostol Genocchi polynomials in variable , order , and level through the following generating functions, defined in a suitable neighborhood of (see, [18, p. 2 Eq , , ])where , , , and .

Based on the previous result, we focus our attention on a new unification of the -analog of the generalized Apostol type polynomials of order and level , defined in [18], by doing some modifications to the generating function linked to the -Mittag-Leffler function (6) through new parameters following the same scheme or procedure applied by [12].

The paper is organized as follows. Section 2 contains some notations, definitions, and properties of the -analogs and some results about -analogs of the Apostol type polynomials. In Section 3, we introduce the unification -analog of the generalized Apostol type polynomials in , parameters , order , and level and their algebraic and differential properties. Finally in the Section 4, we show relations between the -analog of the generalized Apostol type polynomials and the -Stirling numbers of the second kind, the generalized -Bernoulli polynomials of level , the generalized -Apostol type Bernoulli polynomials, the generalized -Apostol type Euler polynomials, the generalized -Apostol type Genocchi polynomials of order and level , and the -Bernstein polynomials.

#### 2. Background and Previous Results

Throughout this paper, we use the following standard notions: , , denotes the set of integers, denotes the set of real numbers, and denotes the set of complex numbers. The -numbers and -factorial numbers are defined, respectively, by El -shifted factorial is defined as The -binomial coefficient is defined by For more information about the -standard definitions and properties see [8, 9, 19].

Furthermore, the -binomial coefficient satisfies the following identity (see [10, p. 483, Eq. ]):The -analog of the function is defined by The -derivative of a function is defined by The -analog of the exponential function is defined in two ways we can see thatTherefore,

For any (see, e.g., [19, p. 76, Eq ]) is called the -gamma function.

The Jackson’s -gamma function is defined by (see [10, p. 490, Eq. ])In (21) we have

For , , , and y the function is defined as (see, e.g., [17, p. 614, Eq. ]) Notice that, when the previous equation is expressed as

Setting y , we can deduceThe -Stirling numbers of the second kind are defined through the following expansion (see, e.g., [20, p. 173, Equ ]):where

Let denote the set of continuous function on . For any , the - is called -Bernstein operator of order for and is defined as (see, e.g., [21, p. 2, Eq ]) where . For , the -Bernstein polynomials of degree or -Bernstein basis are defined by We know that , then and using the identity (13), we have (see [21, p. 6, Eq ])Mahmudov N.I. [22] made a relation between the -Bernstein basis with the -Stirling numbers of the second kind and the -Bernoulli polynomials of order , as follows:
