1 Introduction

Recently,there has been an active research on Appell polynomials.Many authors have studied on Appell polynomials because they have some useful applications in pure and applied mathematics.

Appell polynomials are de fined by

For some special choices of

a

(

t

)

,

we have the well known Bernoulli and Euler polynomials

respectively. The recurrence relations and differential equations of the above polynomials were studied in[21].Besides,differential equation satis fied by Frobenius-Euler and Frobenius-Genocchi polynomials were obtained[58].Bivariate Appell polynomials were de fined by

and corresponding differential equations were obtained in[3].Besides,some extensions of the above family were introduced and differential,integro-differential and partial differential equations satis fied by the extended 2

D

Bernoulli and Euler polynomials were obtained in[57]as a special cases.Moreover,some main properties of the Apostol type extensions of the above polynomials were studied in[38,40,42].Also,

q

-extensions of the Apostol type polynomials were introduced and some addition theorems were obtained in[39].Differential,integro-differential and partial differential equations for the Hermite-based Appell polynomials were obtained in[51].Furthermore,uni fication of the Hermite-based Apostol Bernoulli,Euler and Genocchi polynomials was introduced,and some properties such as symmetry identities and generalized sum of integer powers were obtained in[41].The common property of the Appell polynomial sequence{

)}is

Here,?is the finite difference operator which is

is given by where?=

I

,?=?and

I

is the identity operator.Related interpolation problem of?-Appell sequences was handled in[15].In[15],?-Appell sequences{A(

x

)}were de fined by the power series of the product of

a

(

t

)(1+

ht

)hby

where

a

(

t

)was given by

Twice iterated?-Appell polynomials were introduced and difference equations for a class of twice iterated?-Appell polynomials were obtained in[52].Very recently,the Hahn-Appell polynomials which include the usual,?and

q

-Appell polynomials were introduced and analyzed,corresponding difference equations and

d

-orthogonality problem has been solved for Hahn-Appell polynomials in[54].

On the other hand,Carlitz introduced the degenerate Bernoulli polynomials in[5]

Degenerate Euler polynomials were introduced in[6,27,32],

Degenerate Genocchi polynomials were de fined in[27,37],

Recently,Khan et al.[27]de fined a uni fied class of degenerate Apostol-type polynomials.In the special case

λ

→0

,

uni fied degenerate family reduce to uni fied family satis fied by the Apostol polynomials of order

α.

By monomiality principle,uni fied degenerate Apostol-type polynomials were investigated.Some recurrence relations and explicit representations were obtained.Also,some authors worked on degenerate Bernoulli,Euler and Genocchi polynomials[32,37].The results that are satis fied by the degenerate Bernoulli,Euler and Genocchi polynomials reduce to the results that are satis fied by the usual Bernoulli,Euler and Genocchi polynomials when

λ

→0

.

We observe that the possible de finition of the degenerate Appell polynomials can be the same as the?-Appell polynomials.That is

where

a

(

t

)is given by

This observation motivate us to introduce and study on the?-Gould-Hopper Appell polynomials,since the results will also be reduced to the newly de fined bivariate degenerate versions of many known polynomials.

Gould-Hopper polynomials are given by

which are solutions of the heat equation

Explicitly,they are given by

Degenerate Hermite(or Gould-Hopper)polynomials were introduced in[25]

They reduce to usual case when

λ

→0

.

The explicit form of the degenerate Gould-Hopper polynomials was given in[25]

Because of the same intention that we point out about the motivation of this paper,we will call the polynomials,de fined by

as

h

-Gould-Hopper polynomials.By means of the above polynomials,we de fine?-Gould-Hopper Appell polynomials A(

x,y

;

h

)as

and the?-Gould-Hopper Appell numbers as

In this paper,we introduce degenerate Gould-Hopper Carlitz Bernoulli polynomials of the first kind by

Degenerate Gould-Hopper Carlitz Euler polynomials are introduced as

Degenerate Gould-Hopper Genocchi polynomials are de fined as

Degenerate Gould-Hopper Boole polynomials are de fined as

?-Gould-Hopper Bernoulli polynomials of the second kind are de fined as

By fully degenerating the Gould-Hopper polynomials with a

q

-parameter,Gould-Hopper based fully degenerate poly-Bernoulli polynomials with a

q

-parameter were introduced and addition and difference rule properties were analyzed in[18].Generalized degenerate Gould-Hopper based fully degenerate Bell polynomials were introduced and some representations were obtained for generalized degenerate Gould-Hopper based degenerate Bernoulli,Euler and Genocchi polynomials[17].Note that some properties satis fied by the higher order Boole type polynomials and numbers were obtained.Also,some derivative formulas,recurrence relations and finite combinatorial sums including the Apostol-Euler polynomials,the Stirling numbers and Daehee numbers were given in[53].Degenerate Hermite-Bernoulli polynomials of the second kind[24]were introduced and in the case

λ

→0

,

they reduce to the Hermite Bernoulli polynomials(2

D

Bernoulli polynomials).Some explicit formulas for the higher order degenerate Bernoulli numbers of the first kind and the second kind were obtained and some recurrence formulas were proved.Also,some formulas related with the degenerate Genocchi numbers,degenerate tangent numbers and the coefficient of the higher order degenerate Euler polynomials were deduced in[7].In[15]generalized Bernoulli polynomials of the second kind(?-Bernoulli polynomials of the second kind)were de fined.Some interpolation properties satis fied by these polynomials were obtained.

Using series expansion of(2.1)and applying the Cauchy product,

with the fact that

Comparing equations(2.9)and(2.11),we get the discrete heat equation

Substituting

then dividing both sides of the equation by

6 Concluding Remarks

Some identities and relations involving the modi fied degenerate Hermite-based Apostol-Bernoulli and Apostol-Euler polynomials were obtained in[49].A new uni fied class of degenerate Apostol-type polynomials was introduced.By series de finition and within the context of monomiality principle,degenerate Apostol-type polynomials were investigated.Some recurrence relations and explicit representations were obtained in[27].Taking into consideration of the generating functions satis fied by the?-Gould-Hopper Appell polynomials and using the degenerate uni fied Hermite based exponential function[41,42],the generalized uni fied Hermite-based degenerate Apostol polynomials can be introduced.
