Name
This is quite a simple inequality to prove, and it was most definitely known before the April 2000 article from Bhatia and Davis. Can someone add a reference for this inequality having this name? Preferably from before this article's creating in August 2009. Shuiberts (talk) 21:09, 3 October 2021 (UTC)
