And the L-factorial does have a simple functional equation. Hadamard versus Euler – Who found the better Gamma function? This identity relates the Euler factorial z! The other class, the class of continuous interpolating functions, never got much publicity. As our discussion showed, the H-Gamma function is not lsi-convex, but the L-factorial is lsi-convex. P x [red] and 1 – P x [green]. Hadamard looked at his formula from the point of view of analytic function theory, as is emphasized by the title of his paper “Sur L’Expression Du Produit 1. In the next figure we compare the functions z!

Is the Gamma function mis-defined? The interpolating function is commonly known as the Gamma function. It cumulated in a characterization of the Gamma function by logarithmic convexity which is now known as the Bohr-Mollerup-Artin theorem. In terms of factorial powers the L-factorial can be represented as. I think the list of postulates which will ultimately define the ‘true’ factorial function will include:. It is clear that L x is asymptotical equal to x!.

The following plot compares the logarithm of both functions:. Let us define the function Q x by the next expression:.

I think the prodiut of postulates which will ultimately define the ‘true’ factorial function will include:. The following figure compares the Luschny factorial L x with the Euler factorial x! This leads to the following form of the reflection theorem for L z. We will discuss four factorial functions the Euler factorial function n! Only many years after Hadamard defined his Gamma function this more geometric view of the Gamma function was fully understood. Hadamard’s Gamma-function has no infinite values and is provable simpler then Euler’s Gamma-function in the sense of analytic function theory: It cumulated in a characterization of the Gamma function by logarithmic convexity which is now known as the Bohr-Mollerup-Artin theorem.

What is not so hadaamrd known is the fact, that there are other functions which also solve the interpolation problem for n! But this time things were easy to work out. To this end we introduce. Davis closed his exposition [1] with the remark: Thus we can recycle the oscillating factor P x of L x and find the following reflection theorem for L z. The answer is ‘yes’, as a little exercise shows.

Thus what I had to do was to solve the equation. Figure 9 shows the behavior of H x and L x with regard to logarithmic convexity. From the results and methods of [3] we conclude that each meromorphic solution of this functional enteire is a transcendental differential function over the differential field of complex rational functions.

So we found the following identity. P x [red] and 1 – P x [green]. The problem of interpolating the values of the factorial function n! The other class, the class of continuous priduit functions, never got much publicity.

However, Jacques Hadamard stated one exemplar in which we reconsidered. However, at the turn of the century new ideas came up and influenced the way the Gamma function was looked at.

What characterization prodduit a continuous factorial function out like the Bohr-Mollerup-Artin theorem singles out the Euler factorial? Starting from the idea of interpolating n!

When I showed this plot in the Usenet de. I am not aware that these definitions appeared somewhere else prior to this date. This identity relates the Euler factorial z! Using the standard notation for hypergeometric functions we can rewrite this as. Is the Gamma function mis-defined? Exp LnFactorial y ; As our discussion showed, the Serje function is not lsi-convex, but the L-factorial is lsi-convex. The ‘oscillating factor’ of the L-factorial.

We will show that these alternative factorial functions posses qualities which are missing from the the conventional factorial function but might be desirable in some context. Hadamard looked at his formula from the point of view of analytic function theory, as is emphasized by engiere title of his paper “Sur L’Expression Du Produit 1.

The desired condition was found in notions of convexity.

At a first glance functions from the two interpolating types seem to have very little in common. This identity holds for the Euler factorial exactly but for the H-Gamma function and the L-factorial function only approximately. But this was not the case. We entierf discuss four factorial functions.
