Invariants of groups that are invariant under passage to finite index subgroups
Just a small comment: there's no model category structure on the category of finitely generated groups. A model structure always requires the category to have all limits and colimits. |

Fundamental group of the moduli stack of ordinary generalized elliptic curves
Is it easy to see that the cover obtained by taking roots of (a linear fractional transformation of) the $j$-invariant is not already split by the Igusa tower? |

Finite spectrum annihilated by multiplication by two
Is associativity necessary? It seems to me that this argument shows that any ring spectrum (up to homotopy, and not necessarily associative) with $2 = 0$ cannot be a finite spectrum (which is a more general version of the statement that the mod $2$ Moore spectrum fails to be a ring spectrum). |
