the canonical example is the constructible universe "l" developed by gödel.
o exemplo canônico é o universo construível l desenvolvido por gödel.

for any time constructible function "t"("n"), we have:formula_3.
para qualquer função de tempo construtível "t"("n"), temos que::formula_3.

in particular, zf proves the consistency of z, as the set vω·2 is a model of z constructible in zf.
em particular, zf pode provar a consistência de z por meio da construção do universo de von neumann, vω2, como um modelo .

==construction==a regular heptagon is not constructible with compass and straightedge but is constructible with a marked ruler and compass.
o heptágono regular é o menor polígono regular que não pode ser construído com régua e compasso.

using this, it becomes relatively easy to answer such classical problems of geometry as:"which regular polygons are constructible polygons?
usando esta teoria, torna-se relativamente fácil responder perguntas da geometria clássica tais como::" "quais polígonos regulares são polígonos construtíveis ?

"f"("n") is at least "n", since smaller functions are never time-constructible.note 2.
note que formula_1 é pelo menos "n", uma vez que funções menores nunca serão tempo construtível.
