answered finding the limit $\lim_{a\rightarrow \infty} \frac{a^N}{\log a} \int_{0}^\infty \frac{e^{-x}}{(1+ag(x))^N}dx = c$

comment Fourier series of functions on compact groups
@Mark: if you don't specify an ordering, it is always absolute convergence, or, as the proper term is: summability.

comment Approximations of the identity on Lie groups and homogenous spaces
In the book: Deitmar and Echterhoff: Principles of Harmonic Analysis, this concept is called "Dirac net", or in the case of Lie groups, "Dirac sequence". In the context of Banach algebras, it often goes as "approximate identity".

comment Trace of finitely generated projective module
Great answer, thanks! I actually remember having heard the name Hattori-Stallings before, but somehow I didn't follow it up.

Ok, fine, but the horizontal maps are not isomorphisms.

comment Trace of finitely generated projective module
There are two different zeros around. If you don't take the horizontal arrow to be the same, it won't prove the independence.
