In this note we show a relative version of -set introduced and studied in [12]. We give several characterizations of this property; in particular one of the characterizations is Ramsey theoretical. Also we give a result involving a property of the corresponding mapping between function spaces.
In questo articolo viene presentata una versione relativa del -insieme introdotto in [12]. Vengono date varie caratterizzazioni di questa proprietà; in particolare una delle caratterizzazioni riguarda la teoria di Ramsey. Inoltre viene fornito un risultato che coinvolge una proprietà della corrispondente funzione tra spazi di funzioni.
