CE ÎNSEAMNĂ EXTENSIONALITY ÎN ENGLEZĂ?
Extensionality
În logică, extensivitate sau egalitate extensivă se înțelege principiile care judecă obiectele să fie egale dacă au aceleași proprietăți externe. Acesta este în contrast cu conceptul de intensitate, care se referă la faptul dacă definițiile interne ale obiectelor sunt aceleași.
Definiția extensionality în dicționarul Engleză
Definiția extensivității în dicționar este principiul conform căruia mulțimile pot fi definite numai prin elementele lor, indiferent de modul în care acestea au fost selectate. Astfel {a, b} = {b, a} = {primele două litere ale alfabetului}.
