名詞

(mathematics) A mathematical relationship in which the magnitude of something is proportional to a fixed power of the magnitude of something else (i.e. the relationship takes the form f(x) = a.xᵏ).

日本語の意味

ある量の大きさが別の量の大きさの固定された冪（指数）に比例する数学的関係、すなわち f(x) = a・x^k の形で表される現象や法則。 / 冪乗則（べきじょうそく）

Many empirical networks exhibit a power law in their degree distribution, so the frequency f(k) scales as a·k{-γ}.

多くの実証的ネットワークは次数分布がべき乗則に従い、頻度 f(k) は定数 a に比例して k^{-γ} にスケールする。

意味（1）

(mathematics) A mathematical relationship in which the magnitude of something is proportional to a fixed power of the magnitude of something else (i.e. the relationship takes the form f(x) = a.xᵏ).

the death toll from a large number of small civil wars is lower than that from a few big interstate wars, to say nothing of world wars, consistent with the power-law distribution of deadly quarrels.
