What is this "fundamental pure number" please ?

[stephaneww]

Hi,

I have read here under (2.1) that [math]c^5/(G \hbar \Lambda_{s^{-2}}[/math] is a "fundamental pure number"

It's the word "fundamental" that questions my mind. What is that fondamental notion please?

I've got it. It's just [math]\frac{1}{t_p^2\Lambda_{s^{-2}}}[/math] or [math]\frac{1}{l_p^2\Lambda_{m^{-2}}}[/math], whatever you want. The  factor is [math]8\pi[/math].

Excellent I didn't have time to focus on this but The answer you got sounds correct.
