Fixed-point lemma for normal functions (original) (raw)

Property Value
dbo:abstract The fixed-point lemma for normal functions is a basic result in axiomatic set theory stating that any normal function has arbitrarily large fixed points (Levy 1979: p. 117). It was first proved by Oswald Veblen in 1908. (en) El lema del punto fijo para funciones normales o teorema del punto fijo de Veblen es un teorema básico de la teoría axiomática de conjuntos que afirma cualquier tiene una cantidad arbitrariamente grande puntos fijos,​ demostrado por Oswald Veblen en 1908.
