Talk:Joseph Ritt

Note this
Ritt is said to have started the study of differential algebraic groups. Ritt died in 1951. The study is also said to have been started by Cassidy in 1972. Some one with more knowledge than me will have to speak on this. — Preceding unsigned comment added by 2A00:23C4:4E9F:D101:914E:79F5:53CC:D89F (talk) 10:52, 19 October 2021 (UTC)
