空间有界实数的计算复杂性

Computational Complexity of Space-Bounded Real Numbers

Masaki Nakanishi, Marcos Villagra

摘要:

本文研究了由快速收敛柯西序列表示的可计算实数的空间复杂度。我们表明存在的家庭trascendental数的对数空间可计算的,而不是代数无理数,似乎需要线性空间。通过量化计数集的空间复杂度,刻画了空间有界实数的复杂性。后一个结果引入了一种技术,通过研究其对应的计数集来证明实数的空间复杂度,这可以说是一种更自然的方法。本文的结果为研究超越未知的实数提供了一种新的途径。

英文摘要:

In this work we study the space complexity of computable real numbers represented by fast convergent Cauchy sequences. We show the existence of families of trascendental numbers which are logspace computable, as opposed to algebraic irrational numbers which seem to required linear space. We characterized the complexity of space-bounded real numbers by quantifying the space complexities of tally sets. The latter result introduces a technique to prove the space complexity of real numbers by studying its corresponding tally sets, which is arguably a more natural approach. Results of this work present a new approach to study real numbers whose transcendence is unknown.
