Added what was missing from the definition of the hom sets.

| Jan 29 at 21:47 | comment | added | Ingo Blechschmidt | I really like the papers by Mohamed Barakat, Markus Lange-Hegermann and Sebastian Posur on these topics (explicit computations in Serre quotients and related constructions). Directly relevant to your question is probably arxiv.org/abs/1212.4068, but I also recommend arxiv.org/abs/1003.1943 and arxiv.org/abs/1712.03492. | |
