Un espace topologique X est dit cat

Un espace topologique X est dit catknaire si, pour tout couple (Y, Z)
de parties fermées irréductibles de X telles que Y Z, toute chaîne saturée de parties
fermées irréductibles d'extrémités Y et Z est de longueur codim(Y, Z)

結果 (英文) 1:

ends irreducible closed Y and Z is codim length (Y, Z)

結果 (英文) 3:

a topological space x is said catknaire if, for any pair (y, z) of irreducible closed in x as y, a saturated chain ends closed irreducible parts, and z is a long codim (y, z)
