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:
“He felt with the force of a revelation that to throw up the clods of earth manfully is as beneficent as to revolutionise the world. It was not the matter of the work, but the mind that went into it, that counted—and the man who was not content to do small things well would leave great things undone.”
—Ellen Glasgow (1874–1945)
