乘积σ—代数的一种生成方法

One Method of Generating Product σ —Algebra

本文得到了有限及可数无限维乘积σ—代数的一种新的生成方法，并证明了可数无限维Ｂｏｒｅｌ域具有连续统的势．

In this paper, we obtained a new method of generating finite or countably infinite dimensional product σ —algebra, and proved that countably infinite dimensional Borel field has the cardinality of the continuum.
