Abstract

Els teoremes d’extensió de McShane i Whitney poden generalitzar-se de diverses maneres, permetent estendre funcions des de subespais mètrics a l’espai sencer preservant la constant de Lipschitz. En aquest sentit, proposem introduir una funció ϕ creixent, positiva i subadditiva que, en compondre-la amb una mètrica, s’obté una altra mètrica que millora l’extensió. A més, la noció d’espai d’índexs és introduïda i els resultats d’aquest treball generalitzen els ja coneguts sobre índexs de Lipschitz per al cas dels ϕ-Lipschitz.
