derivability's Usage Examples:

in Peano Arithmetic, one takes modal analogues of the Hilbert-Bernays derivability conditions and Löb"s theorem (if it is provable that the provability.

Causal mechanismAs conventionally conceived by philosophers of science, scientific explanation of a phenomenon was simply epistemic (concerning knowledge), and centered on the phenomenon's counterfactual derivability from initial conditions plus natural laws (Hempel's covering law model).

where D {\displaystyle {\mathcal {D}}} d is the relation of direct derivability.

redundancy of the third, empirical content (CA3), implied by the other three: derivability (CA1), lawlikeness (CA2), and truth (CA4).

Example partial specifications may be the maximum derivability or implementation only for some kernels.

{\displaystyle A_{1}\land \dots \land A_{n}/B} with respect to admissibility and derivability.

formal languages; the turnstile represents syntactic consequence (or "derivability").

pure Prolog programs, "implied by" can be understood very simply as derivability using modus ponens and universal instantiation alone.

derivability is stable under additions to the proof system, whereas admissibility is not.

This is a requirement on derivability, namely, the principle that in a formal system with material implication.

In 1948 when explicating DN model, Carl Hempel and Paul Oppenheim had stated scientific explanation's semiformal conditions of adequacy (CA), but acknowledged redundancy of the third, empirical content (CA3), implied by the other three: derivability (CA1), lawlikeness (CA2), and truth (CA4).

to the first example: a suitable version of the Hilbert-Bernays-Löb derivability conditions holds for the "provability predicate" ω-Prov(A)  ¬ω-Con(PA + ¬A).

Thus, if we are interested only in the derivability of tautologies, not hypothetical judgments, then we can formalize the.
