Abstract:- In this paper we have tried to define two dimensional Kamal transform namely the double Kamal transform of bounded support with the help of Zemanian technique. The integrable Boehmian of double Kamal transform is developed using Mikusinkis theory with some of the properties. The double Kamal transform is extended to generalized function, some properties n distribution sense are obtained and tried to extend this class to integrable Boehmians.

INTRODUCTION

In the field of engineering the ordinary and partial differential equations plays vital role. To solve the differential equation integral transforms are used suitably to convert into simpler form and obtain the solutions easily. The double Natural transform are studied in [2-4], [6] deals with applications of [2-4] where as [9] gives the applications of Kamal transform for single variable functions. The two dimensional Kamal transform of function of two variables can be used to solve partial differential equations.

Let (, ), (, ) be distributions of compact support in E(I x I). We define the convolution of (, ), (, ) as (

)(, ), (, ) = (, ), (1, 2), ( + 1, + 2; (3) where E(I x I) if (1, 2), ( + 1, + 2 E (I x I).

INTEGRABLE BOEHMIAN FOR DOUBLE KAMAL TRANSFORM

Let 1be the space of Lebesgue integrable functions on +; + is the set of positive real numbers then by [5], a sequence

| | < K, for some positive K and all .

(3) |(,)|<|(, )| 0 as for every > 0.

The space of all integrable Boehmians is denoted by 11, which is a convolution algebra with (1) [ ] = []

(2) [ ] + [] = ()+()

()

(3) [ ] [] = [ ]

Lemma: If [

(, ) converges to each compact set x in

+x +.

Proof: We have {} 1 then its double Kamal transform () = converges uniformly to the function of (u, v). Hence for

=

each J x J, is positive on J x J and

K[ (, )] = K[ (, ) ] (4)

Now, we will define the double Kamal transform of an integrable Boehmians as

[ ] = lim(5); where the limit is over compact subsets of x .

Thus, we get a continuous function of double Kamal transform of an integrable Boehmians.

Theorem 10: The double Kamal transform of an integrable Boehmians is well defined.

Theorem 11: The double Kamal transform of an integrable Boehmian is linear on compact sets.

Also, (c) = ] = lim

[= c (); where c and = [ ].

Theorem 12: (Convolution theorem for integrable Boehmians)

Let [

lim hn = 0 on compact sets, again by definition of Kamal transform 0 a.e. in 11 and

Equivalently = [] is zero equivalence class in 1 1 .

is zero quotient of function.

Theorem 14: The generalized double Kamal transform is one-one mapping from 11 into space of continuous functions.

Proof: Let (1) = (2), 1, 2 11 . (1 2) = 0 in , theorem (13)

1 2 = 0 1 = 2.

Theorem 15: The generalized double Kamal transform : 11 is continuous with respect to – converence.

CONCLUSIONS

In this paper, the two dimensional Kamal transform namely double Kamal transform of bounded support is obtained.
