The main purpose of this paper is to introduce and investigate a class of 𝑞-Bernoulli, 𝑞-Euler, and 𝑞-Genocchi polynomials. The𝑞-analogues of well-known formulas are derived. In addition, the 𝑞-analogue of the Srivastava-Pintér theorem is obtained. Somenew identities, involving 𝑞-polynomials, are proved.

1. Introduction

Throughout this paper, we always make use of the classicaldefinition of quantum concepts as follows.

The 𝑞-shifted factorial is defined by

(𝑎; 𝑞)0= 1, (𝑎; 𝑞)

𝑛−1

∏

(1 − 𝑞𝑗𝑎) , 𝑛 ∈ N,

(𝑎; 𝑞)∞=

∏

(1 − 𝑞𝑗𝑎) ,

𝑞 < 1, 𝑎 ∈ C.

(𝑎; 𝑞)𝑛=

𝑘]

𝑞

𝑞(1/2)𝑘(𝑘−1)

(−1)𝑘𝑎𝑘. (2)

The 𝑞-numbers and 𝑞-factorial are defined by

[𝑎]𝑞 =1 − 𝑞𝑎

1 − 𝑞, (𝑞 ̸= 1, 𝑎 ∈ C) ;

[0]𝑞! = 1, [𝑛]𝑞! = [𝑛]𝑞[𝑛 − 1]𝑞!.

(3)

The 𝑞-polynomial coefficient is defined by

[𝑛

=(𝑞; 𝑞)𝑛

(𝑞; 𝑞)𝑛−𝑘(𝑞; 𝑞)𝑘

, (𝑘 ⩽ 𝑛, 𝑘, 𝑛 ∈ N) . (4)

In the standard approach to the 𝑞-calculus two exponen-tial functions are used, these 𝑞-exponential functions andimproved type 𝑞-exponential function (see [1]) are defined asfollows:

The form of improved type of 𝑞-exponential function E𝑞(𝑧)

motivated us to define a new 𝑞-addition and 𝑞-subtraction as

(𝑥 ⊕𝑞𝑦)𝑛

:=

∑

𝑘=0

[𝑛

𝑞

(−1, 𝑞)𝑘(−1, 𝑞)

(−1, 𝑞)𝑘(−1, 𝑞)

2𝑛𝑥𝑘(−𝑦)𝑛−𝑘,

𝑛 = 0, 1, 2, . . . .

(6)

It follows that

E𝑞 (𝑡𝑥)E𝑞 (𝑡𝑦) =

∑

𝑛=0

(𝑥 ⊕𝑞𝑦)𝑛 𝑡𝑛

[𝑛]𝑞!. (7)

The Bernoulli numbers {𝐵𝑚}𝑚≥0

are rational numbers in asequence defined by the binomial recursion formula:

𝑚

∑

𝑘=0

(𝑚

𝑘)𝐵𝑘− 𝐵𝑚= {

1, 𝑚 = 1,

0, 𝑚 > 1,(8)

or equivalently, the generating function

∑

𝑘=0

𝐵𝑘

𝑘!=

𝑡

𝑒𝑡 − 1. (9)

𝑞-Analogues of the Bernoulli numbers were first studiedby Carlitz [2] in the middle of the last century when heintroduced a new sequence {𝛽

𝑚}𝑚⩾0

:

𝑚

∑

𝑘=0

(𝑚

𝑘)𝛽𝑘𝑞𝑘+1

− 𝛽𝑚= {

1, 𝑚 = 1,

0, 𝑚 > 1.(10)

Here and in the remainder of the paper, for the parameter 𝑞we make the assumption that |𝑞| < 1. Clearly we recover (8)if we let 𝑞 → 1 in (10). The 𝑞-binomial formula is known as

(1 − 𝑎)𝑛

𝑞= (𝑎; 𝑞)

The above 𝑞-standard notation can be found in [3].Carlitz has introduced the 𝑞-Bernoulli numbers and poly-

nomials in [2]. Srivastava and Pintér proved some relationsand theorems between the Bernoulli polynomials and Eulerpolynomials in [4]. They also gave some generalizationsof these polynomials. In [4–16], the authors investigatedsome properties of the 𝑞-Euler polynomials and 𝑞-Genocchipolynomials. They gave some recurrence relations. In [17],Cenkci et al. gave the 𝑞-extension of Genocchi numbers ina different manner. In [18], Kim gave a new concept for the𝑞-Genocchi numbers and polynomials. In [19], Simsek et al.investigated the 𝑞-Genocchi zeta function and 𝑙-function by

using generating functions andMellin transformation.Thereare numerous recent studies on this subject by, among manyother authors, Cigler [20], Cenkci et al. [17, 21], Choi et al.[22], Cheon [23], Luo and Srivastava [8–10], Srivastava et al.[4, 24], Nalci and Pashaev [25] Gaboury and Kurt, [26], Kimet al. [27], and Kurt [28].

We first give the definitions of the 𝑞-numbers and 𝑞-polynomials. It should be mentioned that the definition of 𝑞-Bernoulli numbers in Definition 1 can be found in [25].

Definition 1. Let 𝑞 ∈ C, 0 < |𝑞| < 1. The 𝑞-Bernoulli numbersb𝑛,𝑞

and polynomials B𝑛,𝑞(𝑥, 𝑦) are defined by means of the

generating functions:

B̂ (𝑡) :=𝑡𝑒𝑞(−𝑡/2)

(12)

Definition 2. Let 𝑞 ∈ C, 0 < |𝑞| < 1. The 𝑞-Euler numberse𝑛,𝑞

and polynomials E𝑛,𝑞(𝑥, 𝑦) are defined by means of the

generating functions:

Ê (𝑡) :=2𝑒𝑞(−𝑡/2)

Definition 3. Let 𝑞 ∈ C, 0 < |𝑞| < 1.The 𝑞-Genocchi numbersg𝑛,𝑞

and polynomials G𝑛,𝑞(𝑥, 𝑦) are defined by means of the

generating functions:

Abstract and Applied Analysis 3

Note that Cigler [20] defined 𝑞-Genocchi numbers as

𝑡𝑒𝑞 (𝑡) + 𝑒𝑞 (−𝑡)

𝑒𝑞(𝑡) + 𝑒

𝑞(−𝑡)

=

∑

𝑛=0

𝑔2𝑛,𝑞

Then comparing g𝑛,𝑞

with 𝑔𝑛,𝑞, we see that

(−1)𝑛−122𝑛+1

g2𝑛+2,𝑞

= (−𝑞; 𝑞)2𝑛+1

𝑔2𝑛+2,𝑞

. (16)

Definition 4. Let 𝑞 ∈ C, 0 < |𝑞| < 1. The 𝑞-tangent numbersT𝑛,𝑞

are defined by means of the generating functions:

tanh𝑞𝑡 = −𝑖 tan

𝑞 (𝑖𝑡) =𝑒𝑞 (𝑡) − 𝑒𝑞 (−𝑡)

𝑒𝑞(𝑡) + 𝑒

𝑞(−𝑡)

=E𝑞 (2𝑡) − 1

E𝑞(2𝑡) + 1

[2𝑛 + 1]𝑞!.

(17)

It is obvious that, by letting 𝑞 tend to 1 from the left side,we lead to the classic definition of these polynomials:

b𝑛,𝑞:= B𝑛,𝑞 (0) , lim

𝑞→1−

B𝑛,𝑞 (𝑥) = 𝐵𝑛 (𝑥) ,

lim𝑞→1

−

B𝑛,𝑞(𝑥, 𝑦) = 𝐵

𝑛(𝑥 + 𝑦) , lim

𝑞→1−

b𝑛,𝑞= 𝐵𝑛,

e𝑛,𝑞:= E𝑛,𝑞 (0) , lim

𝑞→1−

E𝑛,𝑞 (𝑥) = 𝐸𝑛 (𝑥) ,

lim𝑞→1

−

E𝑛,𝑞(𝑥, 𝑦) = 𝐸

𝑛(𝑥 + 𝑦) , lim

𝑞→1−

e𝑛,𝑞= 𝐸𝑛,

g𝑛,𝑞:= G𝑛,𝑞(0) , lim

𝑞→1−

G𝑛,𝑞(𝑥) = 𝐺

𝑛(𝑥) ,

lim𝑞→1

−

G𝑛,𝑞(𝑥, 𝑦) = 𝐺

𝑛(𝑥 + 𝑦) lim

𝑞→1−

g𝑛,𝑞= 𝐺𝑛.

(18)

Here 𝐵𝑛(𝑥), 𝐸

𝑛(𝑥), and 𝐺

𝑛(𝑥) denote the classical Bernoulli,

Euler, and Genocchi polynomials, respectively, which aredefined by

The aim of the present paper is to obtain some resultsfor the above newly defined 𝑞-polynomials. It should bementioned that 𝑞-Bernoulli and 𝑞-Euler polynomials in ourdefinitions are polynomials of 𝑥 and 𝑦 and when 𝑦 = 0,they are polynomials of 𝑥. First advantage of this approach isthat for 𝑞 → 1−, B

𝑛,𝑞(𝑥, 𝑦) (E

𝑛,𝑞(𝑥, 𝑦), G

𝑛,𝑞(𝑥, 𝑦)) becomes

the classical BernoulliB𝑛(𝑥 + 𝑦) (EulerE

𝑛(𝑥 + 𝑦), Genocchi

G𝑛,𝑞(𝑥, 𝑦)) polynomial and wemay obtain the 𝑞-analogues of

well-known results, for example, Srivastava and Pintér [11],Cheon [23], and so forth. Second advantage is that, similarto the classical case, odd numbered terms of the Bernoullinumbers b

𝑘,𝑞and the Genocchi numbers g

𝑘,𝑞are zero, and

even numbered terms of the Euler numbers e𝑛,𝑞

are zero.

2. Preliminary Results

In this section we will provide some basic formulae for the𝑞-Bernoulli, 𝑞-Euler, and 𝑞-Genocchi numbers and polyno-mials in order to obtain the main results of this paper in thenext section.

Lemma 5. The 𝑞-Bernoulli numbers b𝑛,𝑞

satisfy the following𝑞-binomial recurrence:

2𝑛−𝑘b𝑘,𝑞− b𝑛,𝑞= {

1, 𝑛 = 1,

0, 𝑛 > 1.(20)

Proof. By a simple multiplication of (8) we see that

B̂ (𝑡)E𝑞(𝑡) = 𝑡 + B̂ (𝑡) . (21)

The statement follows by comparing 𝑡𝑚 coefficients.

We use this formula to calculate the first few b𝑘,𝑞:

b2,𝑞=1

b3,𝑞= 0.

The similar property can be proved for 𝑞-Euler numbers

Remark 6. The first advantage of the new 𝑞-numbersb𝑘,𝑞, e𝑘,𝑞, and g

𝑘,𝑞is that similar to classical case odd num-

bered terms of the Bernoulli numbers b𝑘,𝑞

and the Genocchinumbers g

𝑘,𝑞are zero, and even numbered terms of the Euler

numbers e𝑛,𝑞

are zero.

Next lemma gives the relationship between 𝑞-Genocchinumbers and 𝑞-Tangent numbers.

Lemma 7. For any 𝑛 ∈ N, we have

Proof. First we recall the definition of 𝑞-trigonometric func-tions:

𝑒𝑞(𝑖𝑡) + 𝑒

Lemma 9. The odd coefficients of the 𝑞-Bernoulli numbers,except the first one, are zero. That means b

3. Some New Formulae

The classical Cayley transformation 𝑧 →Cay(𝑧, 𝑎) := (1 +𝑎𝑧)/(1−𝑎𝑧)motivated us to derive the formula forE

𝑞(𝑞𝑡). In

addition, by substituting Cay(𝑧, (𝑞 − 1)/2) in the generatingformula we have

B̂𝑞(𝑞𝑡) B̂

𝑞 (𝑡) = (B̂q (𝑞𝑡) − 𝑞B̂𝑞 (𝑡) (1 + (1 − 𝑞)𝑡

2))

×1

1 − 𝑞×

2

E𝑞 (𝑡) + 1

.

(53)

The right hand side can be presented by 𝑞-Euler numbers.Now equating coefficients of 𝑡𝑛 we get the following identity.In the case that 𝑛 = 0, we find the first improved 𝑞-Eulernumber which is exactly 1.

Let us take a 𝑞-derivative from the generating function,after simplifying the equation, by knowing the quotient rulefor quantum derivative, and also using

E𝑞(𝑞𝑡) =

1 − (1 − 𝑞) (𝑡/2)

1 + (1 − 𝑞) (𝑡/2)E𝑞(𝑡) ,

𝐷𝑞(Eq (𝑡)) =

E𝑞(𝑞𝑡) +E

one has

It is clear that E−1𝑞(𝑡) = E

𝑞(−𝑡). Now, by equating

coefficients of 𝑡𝑛 we obtain the following identity.

We may also derive a differential equation for B̂𝑞(𝑡). If

we differentiate both sides of the generating function withrespect to 𝑡, after a little calculation we find that

If we differentiate B̂𝑞(𝑡) with respect to 𝑞, we obtain,

4. Explicit Relationship between the𝑞-Bernoulli and 𝑞-Euler Polynomials

In this section, we give some explicit relationship betweenthe 𝑞-Bernoulli and 𝑞-Euler polynomials.We also obtain newformulae and some special cases for them.These formulae areextensions of the formulae of Srivastava and Pintér, Cheon,and others.

We present natural 𝑞-extensions of themain results in thepapers [9, 11]; see Theorems 17 and 19.
