WebFirst-order logic consists of three sets of symbols. Logical and non-logical symbols in first-order logic FOL syntax can have both logical and non-logical symbols. Logical symbols correspond to logical operators or connectives, such as ∧, ∨, ¬, ⇒, ⇔. They're always interpreted in the sense of the logical operation they represent. In the context of first-order logic, the symbols in a signature are also known as the non-logical symbols, because together with the logical symbols they form the underlying alphabet over which two formal languages are inductively defined: The set of terms over the signature and the set of (well … See more In logic, especially mathematical logic, a signature lists and describes the non-logical symbols of a formal language. In universal algebra, a signature lists the operations that characterize an algebraic structure See more In universal algebra the word type or similarity type is often used as a synonym for "signature".

WebIn logic, the monadic predicate calculus (also called monadic first-order logic) is the fragment of first-order logic in which all relation symbols [clarification needed] in the signature are monadic (that is, they take only one argument), and there are no function symbols.
