Interpretation in Formal Languages
Interpretation assigns meaning to symbols and expressions in a formal language. It defines how a specific set of terms is understood or construed, crucial for logic, programming, and mathematics.
Interpolation Theorem
A theorem stating that if A implies B is provable, a formula C exists using only common symbols. Both A implies C and C implies B are provable, linking the…
Intermediate Logic
Intermediate logic systems bridge the gap between intuitionistic and classical logic. They offer greater expressive power than intuitionistic logic while rejecting certain classical principles, enabling finer distinctions in reasoning.
Intensional Logic
A logic focusing on meaning beyond mere truth values, exploring concepts like belief, necessity, and possibility. It distinguishes between logically equivalent expressions with different modal properties.
Intensional Definition
An intensional definition outlines the core properties and characteristics of a concept, focusing on its inherent meaning rather than listing all its instances. It defines by essence.
