摘要
本文给出了0-1数列若干性质.设a,c分别表示自然数集和实数集的基数,我们有下列结果:(1)C_a^a=c,(2)C_a^0+C_a^1+C_a^2+…+C_a^n+…
In this paper, some properties of 0-1 sequences are given. Let a be the cardinal number of the natural number set and c be the cardinal number of the real number set, then following results are obtained(1)Caa=c,
