| Jan 7, 2013 at 0:22 | comment | added | Reladenine Vakalwe | To be honest, apart from being slightly open to "miracles sometimes occur", I am pretty skeptical about a). I do believe in b) though because it matches with some heuristics I have regarding higher extensions between Vermas (heuristics coming from some brute force computations, but I haven't managed to work out all the extensions in Boe's counterexample, so these may still be "too low rank"). I think I understand Mazorchuk's proof (regarding b)) enough to see that he defers the burden to a result of Backelin. But haven't got my hands on the Backelin paper yet. | |
