Abstract
S. Marcus used a fat Cantor set to show that there is a quasicontinuous function from the interval to that is not Lebesgue measurable. However, his article is not very well known. We give a very simple example of a quasicontinuous non-Lebesgue measurable function from to and we show that there are quasicontinuous non-Lebesgue measurable functions and quasicontinuous Lebesgue measurable functions.

有2c个拟连续的非Lebesgue可测量函数
摘要
S. Marcus使用一个胖Cantor集证明该区间存在拟连续函数 至 Lebesgue无法测量。但是,他的文章不是很出名。我们给出一个非常连续的非莱贝格可测函数的简单例子 至 我们证明有 拟连续非莱贝格可测函数和 准连续Lebesgue可测量的功能。
