COMMENTS

The function f(p) = integral_{x=2..infinity} 1/(x*log(x)^p) has a minimum of -e*log(log(2)) = 0.996285... at p = 1-1/log(log(2)) = 3.728416... [Jean-François Alcover, May 24 2013]

log(log(2)) also equals the median of the Gumbel distribution with location parameter 0 and scale parameter 1. - Jean-François Alcover, Jul 29 2014
