Nov 16, 2010 at 18:05 | comment | added | András Salamon | @Kevin: $m = \omega(k)$ in this context means that $m$ must grow faster than $k$, so $m = \sqrt{k}$ would not be fine. $m = 0.0001 k \log k$ would be fine. | |

Nov 16, 2010 at 16:19 | comment | added | Kevin O'Bryant | @Kaveh, I think you have the question right, except that it isn't necessarily more than $k$. Perhaps he/she would be satisfied with $m=\sqrt{k}$. Perhaps the question is really ``how large can we take $m$''? In any case, all of these variations seem to be answered by Nate below. | |
Nov 16, 2010 at 6:49 | comment | added | Kaveh | I think the question is: we have $k$ i.i.d. standard Gaussian random variables ($X_i$) and using them we want to generate more than $k$ pairwise independent standard Gaussian random variables ($Y_i$) (and we want to do it an efficient way).

Nov 16, 2010 at 4:09 | comment | added | Mike Spivey | @Sleepless: i.i.d. means "independent and identically distributed." | |
Nov 16, 2010 at 4:00 | comment | added | Gjergji Zaimi | I changed the tag since independence-results refers to a different concept of independence. | |
