predicate symbol उदाहरण वाक्य

For predicate logic, the atoms are predicate symbols together with their arguments, each argument being a signature, which may or may not be satisfiable with respect to a given model.
The "'Herbrand base "'is the set of all ground atoms that can be formed from predicate symbols in the original set of clauses and terms in its Herbrand universe.
Let a first-order language be given, with C the set of constant symbols, V the set of ( individual ) variables, F the set of functional operators, and P the set of predicate symbols.
This means that, given an interpretation, a predicate symbol, and " n " elements of the domain of discourse, one can tell whether the predicate is true of those elements according to the given interpretation.
For example, an interpretation " I ( P ) " of a binary predicate symbol " P " may be the set of pairs of integers such that the first one is less than the second.

Because the first-order interpretations described here are defined in set theory, they do not associate each predicate symbol with a property ( or relation ), but rather with the extension of that property ( or relation ).
Consider a first order language for algebraic structures with a monadic predicate symbol S . Then a " fuzzy subalgebra " is a fuzzy model of a theory containing, for any " n "-ary operation h, the axioms
A proposition is ( i ) a predicate symbol applied to the number of terms required by its arity, ( ii ) an operator applied to the number of propositions required by its arity, or ( iii ) a quantifier applied to a proposition.
The interpretation of such a language would define a domain ( universe of discourse ); assign an element of the domain to each individual constant; assign the donation in the domain of some property to each unary ( one-place ) predicate symbol.
#How should we call a first / second order language, whose all symbols are logical ( like connectives quantifiers variables and brackets and identity ), i . e . when it contains neither constants nor function symbols nor predicate symbols ( but does contain the identity symbol )?
