Is there any standard (or reasonably standard) notation for the following function?
Basically, it's
∏(n) - ∏(n-1)
or, which is the same thing,
[itex]\frac{\Lambda(n)}{\log n}[/itex]
(where ∏(n) is the Riemann prime counting function and [itex]\Lambda[/itex](n) is the Von Mangoldt function)
Basically, it's the function that is 1/a if n = p^a, where p is some prime, and 0 otherwise.
I use it all the time, and writing [itex]\frac{\Lambda(n)}{\log n}[/itex] for it is pretty unwieldy. Actually, while on the topic, does it have any sort of standard name?
