In this paper the entire triple sequence space are the generalization of the classical Maddox's paranormed sequence space have been introduced and investigated some topological properties of entire triple sequence space of binomial Poisson matrix of and

A triple sequence (real or complex) can be defined as a function where and denote the set of natural numbers, real numbers and complex numbers respectively. The different types of notions of triple sequence was introduced and investigated at the initial by Sahiner et al. ^{ 1, 2}, Esi et al. ^{ 3, 4, 5, 6, 7, 8}, Dutta et al. ^{ 9}, Subramanian et al. ^{ 10}, Debnath et al. ^{ 11} and many others. Throughout and denote the classes of all, entire and analytic scalar valued single sequences, respectively. We write for the set of all complex triple sequences where the set of positive integers. Then, is a linear space under the coordinate wise addition and scalar multiplication.

Let be a triple sequence of real or complex numbers. Then the series is called a triple series. The triple series is said to be convergent if and only if the triple sequence is convergent, where

A sequence is said to be triple analytic if

The vector space of all triple analytic sequences are usually denoted by . A sequence is called triple entire sequence if

The vector space of all triple entire sequences are usually denoted by The space and is a metric space with the metric

(2) The eigen vectors are orthogonal

(3) is symmetric;

(4) is positive definite.

**Example:** If Hence

and so on.

Now, we define the binomial poisson matrix where

where In this paper, we define the binomial Poisson triple equence spaces and as the set of all sequences whose transforms are in the spaces and respectively, that is

and

Define the triple sequence which will be frequently used as the transform of a triple sequence i.e.,

for all

Now, we may begin with the following theorem which is essential in the text.

for all Consequently

is a Cauchy sequence in the metric space of complex numbers. Since is complete, so

as Hence there exists a positive integer such that

for all In particular, we have

Now

each *m,** **n,** **k*. That is Therefore, is a complete metric space.

**4.2. Theorem.** The entire triple sequence space is linearly isomorphic to

Proof: Now to prove that the existence of a linear bijection between thespaces and with the notation of define the transformation from and by The linearity of is trivial. Furthermore, it is obvious that

for each Then, we have

Thus, we have that and consequently is surjective. Hence, is a linear bijection. Hence the spaces and are linearly isomorphic.

Let be a paranormed space. Recall that a entire triple sequence of the elements of is called a basis for if and only if, for each there exists a unique entire triple sequence of scalars such that

The series which has the sum is then called the expansion of with respect to and written as Since it is known that the poisson matrix domain of a triple sequence space has a basis if and only if has a basis we have the following, because of the isomorphism is onto, defined in the proof of the Theorem 4.2, the inverse image of the basis of the space is a basis of the new space Therefore, we have the following:

**5.1. Theorem.**** **Let for all Define the sequence of the elements of the space by

The sequence is a basis for the space and any has a unique representation of the form

In this section, we state and prove the theorems determining the and duals of the space of non-absolute type.

We shall firstly give the definition of and duals of triple sequence spaces and after quoting the lemmas which are needed in proving the theorems given in this section. The set defined by

The and duals of a triple sequence space are also referred as Köthe-Toeplitz dual, generalized Köthe-Toeplitz dual and Garling dual of a sequence space, respectively

For the give the and duals of the space of non-absolute type, we need the following Lemma.
