Bijektiflik
Bijektiflik, also known as a bijective function or one-to-one correspondence, is a fundamental concept in mathematics, particularly in set theory and abstract algebra. A function f from a set A to a set B is bijective if and only if it is both injective (one-to-one) and surjective (onto).
Injectivity means that distinct elements in the domain set A are mapped to distinct elements in the
Surjectivity means that every element in the codomain set B has at least one element in the
When a function is bijective, it establishes a perfect pairing between the elements of the two sets.
