Lebsgue measure as a function That is a nice counter example! So 1 is false. However,I still think 2 is true. |

metric and measure on the projective space Thank you so much for your answers. I want make sure I understood what you mean in Q3. So a set $E$ in $RP^n$ is measurable if the inverse of $E$ under the projection map is measurable, and the measure of $E$ is defined as the measure of its inverse. Am I right? |

existence of certain weak local homeomorphisms Great! Thank you so much. Your answer reminded me of the Urysohn's lemma for locally compact Hausdorff space (I found it in Folland's real analysis book). |
