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:
“In the small circle of pain within the skull
You still shall tramp and tread one endless round
Of thought, to justify your action to yourselves,
Weaving a fiction which unravels as you weave,
Pacing forever in the hell of make-believe
Which never is belief: this is your fate on earth
And we must think no further of you.”
—T.S. (Thomas Stearns)
