And thirdly, was mathematics decidable?".
An extension of a decidable theory may not be decidable. .
A decision problem which can be solved by an algorithm is called decidable.
A theory is decidable if and only if both it and its complement are semi-decidable.
Since this test is effective,B is decidable and, by Church's thesis, recursive.
Every decidable theory or logical system is semidecidable, but in general the converse is not true;
P is also known to beno larger than PSPACE, the class of problems decidable in polynomial space.
Partially decidable problems and any other problems that are not decidable are called undecidable.
Thesis I. Every effectively calculable function(effectively decidable predicate) is general recursive.
Presburger proved that Peano arithmetic without multiplication was consistent,complete, and decidable.
Every effectively calculable function( effectively decidable predicate) is general recursive italics.
The decision problem of whether the Turing machine with index e will halt on every input is not decidable.
The word decidable stems from the German word Entscheidungsproblem which was used in the original papers of Turing and others.
For example, the set of logical validities V of first-order logic is semi-decidable, but not decidable.
For example, there are undecidable theories in propositional logic,although the set of validities(the smallest theory) is decidable.
Likewise, a reduction computing a noncomputable function can reduce an undecidable problem to a decidable one.
A logical system is decidable if there is an effective method for determining whether arbitrary formulas are theorems of the logical system.
Other languages such as make the value of all expressions in the language decidable so thattype checking can be decidable.
Every inconsistent theory is decidable, as every formula in the signature of the theory will be a logical consequence of, and thus a member of, the theory.
If none of them is equal to k, then k not in B. Since this test is effective,B is decidable and, by Church's thesis, recursive.
Logical systems such as propositional logic are decidable if membership in their set of logically valid formulas(or theorems) can be effectively determined.
A recursive language in mathematics, logic and computer science,is a type of formal language which is also called recursive, decidable or Turing-decidable….
For example, propositional logic is decidable, because the truth-table method can be used to determine whether an arbitrary propositional formula is logically valid.
Since a precise mathematical definition of the term effectively calculable(effectively decidable) has been wanting, we can take this thesis… as a definition of it…"[25].
Haskell's type system, a version of Hindley- Milner, is a restriction of System Fω to so-called rank-1 polymorphic types,in which type inference is decidable.
It is also easy to see that the halting problem is not in NP since all problems in NP are decidable in a finite number of operations, while the halting problem, in general, is undecidable.
A recursively enumerable language in mathematics, logic andcomputer science, is a type of formal language which is also called partially decidable or Turing-recognizable….
Every decidable theory or logical system is semidecidable, but in general the converse is not true; a theory is decidable if and only if both it and its complement are semi-decidable.
A theory(set of formulas closed under logical consequence)in a fixed logical system is decidable if there is an effective method for determining whether arbitrary formulas are included in the theory.
First-order logic is not decidable in general; in particular, the set of logical validities in any signature that includes equality and at least one other predicate with two or more arguments is not decidable. .
