دالة متباينة و شمولية / غامرة في نفس الوقت
A bijection is a mathematical pairing between two groups of objects where each item in one group matches with exactly one item in the other group, with no leftovers or duplicates on either side. This concept matters because it provides a precise way to establish when two collections have the same size, even when dealing with infinite sets, and serves as a foundation for understanding deeper mathematical relationships between different structures.

في الرياضيات، الدالة التقابلية (بالإنجليزية: Bijective Function) أو ببساطة، التقابل، هي دالة رياضية من مجموعة X إلى مجموعة Y حيث كل عنصر y من المجموعة المستقر Y ،هناك سابق واحد فقط x من المجموعة المنطلق X حيث يكون : f(x) = y أي أن y هي صورة x بالدالة f.
