在度量几何中的网的数论模拟提出了新的问题,并在组合和加法数论中产生了新的结果。例如,对于一个固定的整数g ≥ 2,研究关于生成集Ag = {0}<${± gi:i = 0,1,2,.}的整数加性群中的h-网需要关于Ag的整数的字长的知识。描述了整数的g-adic表示,其在算法上产生最短长度的表示。还讨论了加法补和加法渐近补,以及与之相关的极小性问题。
The number theoretic analog of a net in metric geometry suggests new problems and results in combinatorial and additive number theory. For example, for a fixed integer g ≥ 2, the study of h-nets in the additive group of integers with respect to the generating set Ag = {0} ∪ {± gi : i = 0, 1, 2, …} requires a knowledge of the word lengths of integers with respect to Ag. A g-adic representation of an integer is described that algorithmically produces a representation of shortest length. Additive complements and additive asymptotic complements are also discussed, together with their associated minimality problems.
