Hello
Determine whether the following series is convergent or divergent:
This one makes me crazy!
How to deal with it ?!
The power e is on the whole ln.
I may be being a bit dense here, but what does the notation denote? Is this a fractionally iterated logarithm, a fractional derivative (not likely I would have thought), abused notation for , ... ?
By the way as grows more slowly than any positive power of , so does and in particular for large enough there exists a such that , and so the series diverges.
