Remember the multiplicative factor he introduces, which threw me for a little bit. Gerhard "Carefully Reading Between The Ticks" Paseman, 2014.06.20 | |
| Jun 21, 2014 at 2:59 | comment | added | Gerhard Paseman | This is related to distribution of totatives of n. Canadian Journal of Math. in 1955 has an article by D.H. Lehmer of a similar title where he looks at how the distribution varies from the average in the interval (qn/k, (q+1)n/k) for various small k including your case of k=4. You should find this and later articles (e.g. Codeca and Nair) helpful for your D(n). MathOverflow questions 88777 and 37679 are favorites of mine, which partly address your question and show related material. Gerhard "I'm Also Finding It Useful" Paseman, 2014.06.20 | |
