K-function
The function is in mathematics a special function, which is commonly referred to. It generalizes the hyper Faculty on the complex numbers.
The Hyper factorial of a natural number is defined by
For the function now is to apply
And it should be extended to the number area of the complex numbers.
Definitions
One possible definition of the function is:
Where is the complex generalization of the binomial coefficients and Γ the gamma function.
Another possibility is
Where for the Riemann zeta function and the Hurwitz zeta function are (there are the derivatives of each hand. )
The relationship of function to the gamma function and the barnesschen function is defined by the formula
Expressed.
Values
For natural values of the K- function agree by definition the same as the value of the hyper factorial function. The first of these values are
The value is explicitly given by
Where is the constant of Glaisher - Kinkelin.
Other correlations
Applies with the barnesschen G function
For all
Benoit Cloitre 2003 showed the following formula:
