The small Veblen ordinal or or is the limit of ordinals that can be described using a version of Veblen functions with finitely many arguments. It is the ordinal that measures the strength of Kruskal's theorem. It is also the ordinal type of a certain ordering of rooted trees (Jervell 2005).
Famous quotes containing the word small:
“I went to a literary gathering once.... The place was filled with people who looked as if they had been scraped up out of drains. The ladies ran to draped plush dresses—for Art; to wreaths of silken flowerets in the hair—for Femininity; and, somewhere between the two adornments, to chain-drive pince-nez—for Astigmatism. The gentlemen were small and somewhat in need of dusting.”
—Dorothy Parker (1893–1967)
