bijektivna
Bijektivna is a term used in several Slavic languages to describe a property of a function, map, or transformation. In English, it corresponds to the word bijective. A bijektivna funkcija (bijective function) is one that is both injective (one-to-one) and surjective (onto). Equivalently, it establishes a one-to-one correspondence between the elements of its domain and codomain.
A function f: A -> B is bijektivna if for every y in B there exists a unique
Examples include f(x) = x + 1 from the real numbers to the real numbers, which is bijektivna;
Consequences of bijectivity include the equality of cardinalities of domain and codomain and invertibility of the
