# Did the mathematician Garrett Birkhoff ever work with or mention Feynman's path integrals?

Did Garrett Birkhoff ever work with Feynman's path integral? Did he ever work in his Many-Histories interpretation? Or at least, did he mention it in any of his articles?

• Why do you think he might have? – kimchi lover Apr 27 at 22:39
• Not as far as I know. Garrett Birkhoff was my Ph.D. advisor. A MathSciNet search shows that there is no paper by Birkhoff where the word "Feynman" is mentioned in the review. Birkhoff has a 1935 paper about infinite-dimensional integrals, but that was before Feynman's integral. – Gerald Edgar Apr 28 at 13:01
