comment Question About Harmonic Function Theory
@Wasilewki: It's probably a possible solution, but unfortunately I have no idea what Ito's lemma, Wiener process nor supermartingale are... Thanks anyway ! ( I was thinking about some PDE method or something)

@Kofi: Your example is indeed wrong, since it is not non-negative...

Thanks for your quick reply ! ! The problem is that I can't figure out how to "derive" the equality I mentioned... What are they doing in order to get it? Thanks again !!!

comment Group Theory- Zassenhaus Filtration & Other Filtrations
So what you're actually saying is that the derived series is contained in the zassenhaus filtration ? What about any results about bounding the other direction ? (something like - the n'th term of the zass. filtration is contained in the 10000n's term of the derived series)? Have you got any idea? Thanks a lot again !

Thanks a lot Mark Sapir! Have you got any idea if one of these references contains some relation between the derived series and the Zass. Filtration?

comment Further Questions Regarding Cohomolgoy Theory Of Sheaves
Thanks again Gunnar, regarding 1- But what do you mean by $f_* \mathbb{C} $ ? It seems not suitable for the direct image sheaf case regarding 3- I know the definition of the topological Euler char of $X$. But in your previous answers, you wrote: $\chi(\mathbb{C}^{\oplus d }) = d \chi(Y) $ . How did you get this result? Thanks !
