invertible
Significado: Capable of being reversed or inverted. In mathematics, describes a function or matrix for which an inverse exists, allowing the original operation to be undone.
In linear algebra, an invertible matrix (also called non-singular) has a unique inverse such that their product yields the identity matrix. Invertibility is a fundamental property that determines whether systems of equations have unique solutions. In cryptography, invertible transformations are essential — encryption must be invertible so that decryption can recover the original message. Outside mathematics, the word appears in discussions of reversible processes and policies.
Ejemplos
- The matrix is invertible if and only if its determinant is non-zero, a condition easily verified computationally. 当且仅当矩阵的行列式不为零时,该矩阵是可逆的,这一条件可以通过计算轻松验证。La matriz es invertible si y solo si su determinante es distinto de cero, una condición fácilmente verificable computacionalmente.行列はその行列式がゼロでない場合に限り可逆であり、この条件は計算で容易に確認できる。행렬은 그 행렬식이 0이 아닌 경우에 한하여 가역이며, 이 조건은 계산으로 쉽게 확인할 수 있다.
- The encryption function must be invertible so that the intended recipient can recover the original plaintext. 加密函数必须是可逆的,以便预期的接收者能够恢复原始明文。La función de cifrado debe ser invertible para que el destinatario previsto pueda recuperar el texto original.暗号化関数は可逆でなければならず、そうすることで意図された受信者が元の平文を復元できる。암호화 함수는 가역이어야 하며, 그래야 의도된 수신자가 원래의 평문을 복원할 수 있다.
- The policy changes proved not to be easily invertible, as contractual obligations had already been entered into. 事实证明,政策变更不容易逆转,因为合同义务已经签订。Los cambios de política demostraron no ser fácilmente invertibles, ya que ya se habían contraído obligaciones contractuales.その政策変更は容易には元に戻せないことが判明した。すでに契約上の義務が発生していたためである。그 정책 변경은 쉽게 되돌릴 수 없는 것으로 판명되었다. 이미 계약상의 의무가 발생해 있었기 때문이다.

Origen e historia
From Latin invertere (to turn upside down, reverse), from in- (into, upon) + vertere (to turn). The mathematical sense emerged in the 19th century with the formalisation of matrix algebra.
