Keeping up with the Schwar(t)zes
For future reference, reminded by a recent webcomic:
- There is no ‘t’ in Cauchy–Schwarz. It is named after Hermann Schwarz (1843–1921), who rediscovered it in 1888. His other work includes some stuff in complex analysis: Schwarz lemma, Schwarz–Christoffel mapping, a theorem about symmetry of second derivatives, etc.
- All other (mathematical) Schwar(t)zes have ‘t’s.
- There’s Jack Schwartz (1930–2009), mathematician–and–computer scientist, who was Gian-Carlo Rota’s advisor and co-wrote the monumental three-volume work on Linear Operators (“Dunford and Schwartz”). And he’s also the name in the Schwartz-Zippel lemma (“Or the Schwartz-Zippel-DeMillo-Lipton Lemma.”)
- There’s Laurent Schwartz (1915–2002), who was at ENS, worked on the theory of distributions, and won the Fields Medal in 1950. (“Schwartz space”)
Those are the major ones, I think.
