U+22A7 "⊧" Models Unicode Character

U+22A7 "⊧" Models is a mathematical symbol primarily used in logic and model theory to represent the relationship of logical consequence or semantic entailment. In formal notation, it indicates that a set of premises or axioms semantically implies a particular conclusion, meaning that every interpretation or model that satisfies the premises also satisfies the conclusion. This symbol is distinct from the similar looking "turnstile" (⊢) which denotes syntactic provability, as ⊧ focuses on the truth of statements in all possible models. It plays a fundamental role in defining the semantics of formal languages, particularly in first-order logic and related disciplines.
