This is a thorny issue. I did research on Davydov solitons, and visited Davyodv's institute in Feofaniia, Kyiv, in 1989. People there - especially the Ukrainians - clearly distinguished between Russian and Ukrainian colleagues, based (I believe) mostly on which language they preferred. Davydov was absolutely seen as Russian. I can read that he was born on Crimea, and without getting into the current situation, Crimea was at the time of his birth, and until 1954, Russian. W we currently present him as "Soviet and Ukrainian", but should we somehow include "Russian"? Nø (talk) 10:15, 20 March 2023 (UTC)Reply
