摘要:

该文研究了 $\mathbb{R}$ 上几类权函数为加倍权的条件. 首先给出了 $\mathbb{R}$ 上单调权函数为加倍权的充要条件; 其次刻画了 $\mathbb{R}$ 上分段单调权函数为加倍权的条件; 最后讨论了 $\mathbb{R}$ 上分段加倍权函数为加倍权的条件.

关键词: 权函数, 加倍权, 加倍测度

Abstract:

The paper will study several kinds of doubling weights on $\mathbb{R}$. We firstly give sufficient and necessary conditions on which monotonic weights are doubling. Secondly we describe doubling piecewise monotonic weights. At last, we discuss doubling weights which are piecewise doubling on $\mathbb{R}$.

Key words: Weight function, Doubling weight, Doubling measure
