#Erinnerung und #Begegnung: www.zweitzeugen.de: der Verein hat das Konzept Zweitzeugen hervorgebracht, maßgeblich vorangetrieben durch Eva Weyl, Der Vater von Eva Weyl ging in Kleve zur Schule. Der Großvater führte das Kaufhaus #Weyl in #Kleve. Eva Weyl hatte eine Videobotschaft zur Gedenkveranstaltung in der Realschule am 27. Januar 2025 geschickt.

Quote of the day: "Ultimately it must turn out that action densities must not be glued together additively. I too, concocted various things, but time and again I sank my head in resignation" 1918 #Einstein in a letter to #Weyl. #GeneralRelativity #Physics

- #Weyl group W is isomorphic to the symmetric group Sn on n letters, with #permutation matrices as representatives

Anyone out there read 'Radical Markets' by #posner and #weyl ? http://radicalmarkets.com/ can you recommend? I'm mostly interested as Weyl developed and in the book promotes #quadraticVoting

#Hodge considered new proof much superior, a serious flaw was discovered by Bohnenblust. Independently, #Weyl and Kunihiko Kodaira modified Hodge's proof to repair error. This established Hodge's sought-for #isomorphism between harmonic forms and #cohomology classes.

The group of isometries of (roots:non 0 vectors )generated by reflections through hyperplanes associated to the roots of Φ is called the #Weyl group of Φ.
