biconditional logic
[baɪ-kən-ˈdɪ-ʃə-nəl ˈlɑ-dʒɪk]
noun
lógica bicondicional
1. A logical connective that establishes a relationship between two propositions where both are true or both are false simultaneously; represents the equivalence operator (if and only if).
In biconditional logic, 'P if and only if Q' is true when P and Q have the same truth value.
Na lógica bicondicional, 'P se e somente se Q' é verdadeiro quando P e Q têm o mesmo valor de verdade.
2. A formal system or operation in mathematics and computer science where a statement is true only when both sides of the conditional have identical truth conditions.
The biconditional logic operator is symbolized as P ↔ Q or P ≡ Q.
O operador de lógica bicondicional é simbolizado como P ↔ Q ou P ≡ Q.
This is technical terminology primarily used in academic and professional contexts within mathematics, computer science, and formal logic. It is identical across English and Portuguese-speaking academic communities, reflecting the universal nature of formal logic. In Brazil, this term is standard in engineering and computer science programs. The concept is essential for understanding database queries, programming conditionals, and mathematical proofs.
