The successor function, denoted S(n) = n + 1, is a foundational concept in arithmetic and logic, defining the next…
A subordinate connective is a logical operator appearing within the scope of another logical operator in a compound proposition. It…
A relation R is strongly connected if for any two elements x and y, either x is related to y…
Strong induction strengthens the inductive hypothesis, allowing the assumption that the proposition holds for all smaller cases. This powerful technique…
A strong counterexample in intuitionistic logic disproves an instance of the law of excluded middle. It's a proof of negation,…
Strong completeness in logic means that if a formula is true in all interpretations (semantically valid), it can be proven…
Soundness ensures that a logical system's derived theorems are always true under any interpretation. It's a fundamental property for reliable…
The Skolem paradox highlights a contradiction between intuition and the Skolem-Lowenheim theorem. It shows that countable models can exist for…
