| Mar 31, 2018 at 5:22 | comment | added | Nik Weaver | @Suvrit Yes, even though the question isn't research level I don't object too strongly because there can still be interesting answers, such as yours. | |
| Mar 30, 2018 at 23:09 | comment | added | Suvrit | @NikWeaver I totally agree with you, which is why I left a comment to it (but then seeing that others deemed it worthy of an answer, I elevated my comment to an answer); this one is likely not even the only question on MO that can be answered by von Neumann's inequality, there's been several others in the past I think. Oh well.... | |
