| Jun 2, 2011 at 5:56 | comment | added | Martin Sleziak | @Kevin: I tried to google a little, but I only found results concerning asymptotitc and logarithmic density. Luca-Pomerance-Porubsky: Sets with prescribed arithmetic densities math.dartmouth.edu/~carlp/LuPoPor08-2.pdf Luca-Porubsky: On asymptotic and logaritmic densities sav.sk/journals/uploads/0131154306POLU06.ps Do you happen to have a reference for that results? (Maybe you have slides or notes from the talk...) | |
| May 29, 2011 at 22:48 | comment | added | Kevin O'Bryant | I think Luca (and others) is the author of a recent (last 10 years) paper that proves that "for any choice of $0\leq a \leq b \leq c \leq d \leq 1$ ...". I just sat in a talk of Renling Jin's (perhaps joint work with Grekos) where he announced a simplification and extension of this (several other measures involved also simultaneously). | |
