- Around the word, formal, actual, non, predicate, formula and itself stand out and add context to how "provability" is used.
- Recognizable usage signals include about the provability of statements and about formal provability within these. That gives this page its own corpus information beyond isolated example sentences.
- By corpus frequency, "provability" sits close to words such as aanand, abcd and abdurrahman, which helps place it inside the broader word index.
Example types with provability
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
The incompleteness theorems are about formal provability within these systems, rather than about "provability" in an informal sense. (18 words)
Rather than depend on provability of these axioms, science depends on the fact that they have not been objectively falsified. (20 words)
The relationship between provability in classical (or nonconstructive) systems and provability in intuitionistic (or constructive, respectively) systems is of particular interest. (21 words)
They are particularly concerned with the interpretation of a Gödel sentence for an ω-inconsistent system as actually saying "I am not provable", since the system has no models in which the provability predicate corresponds to actual provability. (38 words)
Provability and theoremhood To establish a mathematical statement as a theorem, a proof is required, that is, a line of reasoning from axioms in the system (and other, already established theorems) to the given statement must be demonstrated. (38 words)
The notion of provability itself can also be encoded by Gödel numbers, in the following way: since a proof is a list of statements which obey certain rules, the Gödel number of a proof can be defined. (37 words)

The relationship between provability in classical (or nonconstructive) systems and provability in intuitionistic (or constructive, respectively) systems is of particular interest.
They are particularly concerned with the interpretation of a Gödel sentence for an ω-inconsistent system as actually saying "I am not provable", since the system has no models in which the provability predicate corresponds to actual provability.
Also, it makes the concept of "provability," and thus of "theorem," a clear concept that only depends on the chosen system of axioms of the theory, and not on the choice of a proof system.
Crucially, because the system can support reasoning about properties of numbers, the results are equivalent to reasoning about provability of their equivalent statements.
Gödel was a platonist and therefore had no problems with asserting the truth and falsehood of statements independent of their provability.
In the course of his research, Gödel discovered that although a sentence which asserts its own falsehood leads to paradox, a sentence that asserts its own non-provability does not.
Provability and theoremhood To establish a mathematical statement as a theorem, a proof is required, that is, a line of reasoning from axioms in the system (and other, already established theorems) to the given statement must be demonstrated.
Questions about the provability of statements are represented as questions about the properties of numbers, which would be decidable by the theory if it were complete.
Questions about the provability of statements within the system are represented as questions about the arithmetical properties of numbers themselves, which would be decidable by the system if it were complete.
Rather than depend on provability of these axioms, science depends on the fact that they have not been objectively falsified.
The name Bew is short for beweisbar, the German word for "provable"; this name was originally used by Gödel to denote the provability formula just described.
The notion of provability itself can also be encoded by Gödel numbers, in the following way: since a proof is a list of statements which obey certain rules, the Gödel number of a proof can be defined.
