我们使用数字 0、+/- 1 研究二进制展开式中整数 n 的表示。我们分析最小“权重”(= 非零数字的数量)的此类表示的平均数量。该平均值的渐近主项涉及周期性振荡函数,对此进行了详细分析。主要工具是构建 [-1,1] 上的度量,对表示的数量进行编码。
We study representations of integers n in binary expansions using the digits 0, +/- 1. We analyze the average number of such representations of minimal "weight" (= number of non-zero digits). The asymptotic main term of this average involves a periodically oscillating function, which is analyzed in some detail. The main tool is the construction of a measure on [-1,1], which encodes the number of representations.
