可计算概率空间中的可计算随机性和投注

Computable randomness and betting for computable probability spaces

Jason Rute

摘要:

与马丁-勒夫随机性和施诺尔随机性不同,可计算随机性在康托空间之外还没有定义,除了一些特殊的情况。本文给出了这样一个定义(实际上是几个等价的定义),并进一步给出了从Cantor空间到任意可计算概率空间中抽象随机性的“逐位”定义的一般方法。同样的方法也适用于给可计算的概率空间的可计算和Schnorr随机性的机器表征,扩展了以前已知的结果。本文提出了一种新的随机性-自同态随机性-作者希望它能有助于解决Kolmogorov-Loveland随机性是否等价于Martin-Löf随机性的问题。最后一部分是对未来研究的展望。

英文摘要:

Unlike Martin-Löf randomness and Schnorr randomness, computable randomness has not been defined, except for a few ad hoc cases, outside of Cantor space. This paper offers such a definition (actually, several equivalent definitions), and further, provides a general method for abstracting "bit-wise" definitions of randomness from Cantor space to arbitrary computable probability spaces. This same method is also applied to give machine characterizations of computable and Schnorr randomness for computable probability spaces, extending the previously known results. The paper contains a new type of randomness---endomorphism randomness---which the author hopes will shed light on the open question of whether Kolmogorov-Loveland randomness is equivalent to Martin-Löf randomness. The last section contains ideas for future research.
