Creation of a summation formula enmeshed with contiguous relation.

[section]1. Introduction

Generalized Gaussian hypergeometric function of one variable is defined by

[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] (1)

where the parameters [b.sub.1], [b.sub.2], ... ,[b.sub.B] are neither zero nor negative integers and A, B are nonnegative integers.

Definition 1.1. Contiguous relation W is defined as follows

[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] (2)

Definition 1.2. Recurrence relation of gamma function is defined as follows

[GAMMA](z + 1) - z[GAMMA](z). (3)

Definition 1.3. Legendre duplication formula t3l is defined as follows

[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] (4)

[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] (5)

[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] (6)

Definition 1.4. Bailey summation theorem M is defined as follows

[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] (7)

[section]2. Main results of summation formula

[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]

Derivation of result (8):

Putting

b = -a -47, z = -1/2

in established result (2), we get

[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]

Now proceeding same parallel method which is applied in [6], we can prove the main formula.
