摘要
集合的特征函数是实变函数中一类特别重要的函数。本文研究了集合特征函数的可测性、(L)可积性、(R)可积性、连续性和半连续性。
The characteristic function of set is a very important kind in rear function, in this paper, I explore the measurability, the L-integrability, the R-integrability, the continuity and the half continuity of the characteristic function of set .
