Hilbert–Bernays derivability conditions

Target entity: Hilbert–Bernays derivability conditions
Context triple: [Löb's theorem, relatedTo, Hilbert–Bernays derivability conditions]

• A. Gentzen’s consistency proof for arithmetic
  Gentzen’s consistency proof for arithmetic is a landmark 1930s result in proof theory that established the consistency of Peano arithmetic using transfinite induction up to the ordinal ε₀.
• B. Hilbert-style deductive systems
  Hilbert-style deductive systems are axiomatic proof systems in mathematical logic that use a small set of axiom schemas and a few inference rules (typically including modus ponens) to derive theorems in formal theories such as Zermelo–Fraenkel set theory.
• C. Recherches sur la théorie de la démonstration
  Recherches sur la théorie de la démonstration is Jacques Herbrand’s foundational work in mathematical logic, introducing key results in proof theory and what is now known as Herbrand’s theorem.
• D. Hilbert’s program
  Hilbert’s program was an influential early-20th-century initiative in the foundations of mathematics that sought to formalize all of mathematics and prove its consistency using finitistic methods.
• E. Löb's theorem
  Löb's theorem is a fundamental result in mathematical logic that characterizes when a sufficiently strong formal system can prove statements about its own provability, closely refining the insights of Gödel’s incompleteness theorems.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Hilbert–Bernays derivability conditions
Target entity description: The Hilbert–Bernays derivability conditions are a set of formal requirements on provability predicates in arithmetic that underpin key results in mathematical logic, including Gödel’s incompleteness theorems and Löb’s theorem.
