Minor points
Generally we use displaystyle (we have the shortcut \ds here) in any math block with big operators like \sum, \prod, \bigoplus, etc. and colons before displayed blocks. Also bear in mind sources are compulsory for all definitions but optional for theorems. You're doing quite well form-wise so far. Caliburn (talk) 15:24, 24 July 2021 (UTC)
