停机问题是否可以非算法有效地解决?哥德尔句是否在NP中,而不是在P中?

Is the Halting problem effectively solvable non-algorithmically, and is the Goedel sentence in NP, but not in P?

Bhupinder Singh Anand

摘要:

我们考虑一个算术关系是图灵可判定的当且仅当它是PA-可证公式的标准表示,这个算术关系对任何给定的自然数到它的自由变元的赋值成立.我们表明,在经典上,这样的论文是,既,不可验证和不可反驳的,而且,它意味着图灵命题是假的,哥德尔的算术谓词R(x),作为一个布尔函数,是在复杂性类NP,但不是在P;和停机问题是有效地解决,虽然不是算法。

英文摘要:

We consider the thesis that an arithmetical relation, which holds for any, given, assignment of natural numbers to its free variables, is Turing-decidable if, and only if, it is the standard representation of a PA-provable formula. We show that, classically, such a thesis is, both, unverifiable and irrefutable, and, that it implies the Turing Thesis is false; that Goedel's arithmetical predicate R(x), treated as a Boolean function, is in the complexity class NP, but not in P; and that the Halting problem is effectively solvable, albeit not algorithmically.
