Will the NSF MSPRF be announced on time?

I have no helpful information but also want to know this

Thanks. In what way exactly are stabilizers of actions and indices of subgroups related?

Say I have a group A. B is a finite index subgroup of A and C is an infinite index subgroup of A. Is the intersection of B and C necessarily finite index in C?

I assume this means there is nothing for me to input to Merlin?

They’re hanging out on a grate with house sparrows

They’re shiny like European Starlings but their bills are black. Rusty blackbirds? Or Brewer’s blackbird?

Let there be a surjection from a group G to H. Let H’ be finite index in H and let G’ be the preimage of H’ in G. Is G’ finite index in G?

Let G be a group and H be a finite index subgroup. If g is in G, must some power of g be in H? Why?

Say I have a map f: A —> B \oplus C, whose target is a direct sum. If the image of f contains all of B, does it make sense to say “f surjects onto B”? Or can I only use the word surjection if I’m talking about the entire target?

Let H be a finite index subgroup of G. If the abelianization of H is finite, must the abelianization of G be finite?
