| May 14, 2010 at 17:50 | comment | added | Qfwfq | The equality I wrote above absolutely doesn't work! For example, if $G$ has positive dimension, the "expected" dimentions of the two sides do not match. | |

| May 14, 2010 at 17:07 | comment | added | Qfwfq | I mean, if $G$ acts on $X$ and $Y$, and diagonally on $X\times Y$, then $(X\times Y)/G\cong (X/G)\times (Y/G)$. Is it correct, right? | |
