Omega Constant




:\Omega\,\exp(\Omega)=1.

It is the value of ''W''(1) where ''W'' is Lambert's W Function . The name is derived from the alternate name for Lambert's ''W'' function, the ''Omega function''.

The value of Ω is approximately 0.5671432904097838729999686622. It has properties that are akin to those of the Golden Ratio , in that

: e^{-\Omega}=\Omega,

or equivalently,

: \ln (1/\Omega) = \Omega.

One can calculate Ω Iteratively , by starting with an initial guess Ω0, and considering the Sequence

: \Omega_{n+1}=e^{-\Omega_n}.

This sequence will Converge towards Ω as ''n''→∞.


IRRATIONALITY


Ω can be proven Irrational from the fact that E is Transcendental ; if Ω were rational, then there would exist integers ''p'' and ''q'' such that

: rac{p}{q} = \Omega

so that

: 1 = rac{p e^{ rac{p}{q}}}{q}
: e = \sqrt {Link without Title} { rac{q^q}{p^q}}

and e would therefore be algebraic of degree ''p''. However e is transcendental, so Ω must be irrational.

Ω is in fact Transcendental as the direct consequence of Lindemann–Weierstrass Theorem .
