添加一个随机实数

Adding one random real

Tomek Bartoszyński, Andrzej Rosłanowski, Saharon Shelah

摘要:

研究了增加一个随机实数后测度和范畴的基数不变量。特别地,我们证明了覆盖所有连续函数的图所需的平面的测度零子集的数目可能很大,而测度的覆盖很小。

英文摘要:

We study the cardinal invariants of measure and category after adding one random real. In particular, we show that the number of measure zero subsets of the plane which are necessary to cover graphs of all continuous functions maybe large while the covering for measure is small.
