Finiteness of $H_1 \backslash G / H_2$ and the geometry of the orbits
@paulgarrett I believe $T_2 \backslash GL_2 /T_2$ is not finite, as $a_{11}a_{22}/a_{12}a_{21}$ is invariant.

Is the induced map between etale cohomology groups independent of the compactification?
Thank you ! How about the integral coefficient cohomology group, which may contain some torsion elements?

Algorithmically computing Weil cohomology groups
For betti numbers modulo $\ell$ (which is equal to the original Betti number for large $\ell$), see arxiv.org/abs/1304.5376.

Thank you! If you want to spread out, then smooth base change may also be necessay. I am interested in abstract Weil cohomology as I hope there are more of them.

Smallest class of linear algebraic groups that is closed under intersections and contains all reductive groups
I am a little careless.. thank you anyway.
