On the one hand, there is some prima facie reason for thinking that only
decidable concepts can be possessed implicitly.
Now, we can show that convergence and divergence are
decidable for POA[[pi].sub.ri] and PA[pi].
Thus, intensional FOL has a simple Tarski first-order semantics, with a
decidable unification problem, but we need also the actual world mapping which maps any intensional entity to its actual world extension.
Nevertheless, the answer to the question is always only a form of not answering the question in any
decidable way.
This includes automatically verifying that congruence closure, the theory of tree-embeddings, and the theory of nonstrict partial orderings are polynomial time
decidable, that propositional logic is in both co-NP and exponential time, and that the first-order theory of total orderings is in co-NP.
Satisfiability (validity) is a
decidable problem for a logic if there exists a decision procedure for the satisfiability (validity) of every formula of the logic.
The 1-letter nonemptiness problem for a LAA is
decidable in time that is linear in both its hesitant size and its degree.
Given these definitions, the first thing to note is that equality between reals is not a
decidable relation: [Mathematical Expression Omitted] is not a theorem of constructive mathematics.
Since the pure domain theory is
decidable, we can effectively determine whether this value for OUTPUT represents a number.
This account applies both to
decidable and undecidable sentences.
Where it is
decidable is with regard to the locations he did not mention: for example, the neck.
