Networks with vertices with degree higher than the structural cut-off will display structural disassortativity. ==Definition== The structural cut-off is a maximum degree cut-off that arises from the structure of a finite size network. Let $E\_$ be the number of edges between all vertices of degree $k$ and $k\text{'}$ if $k\; \backslash neq\; k\text{'}$, and twice the number if $k=k\text{'}$. Given that multiple edges between two vertices are not allowed, $E\_$ is bounded by the maximum number of edges between two degree classes $m\_$. Then, the ratio can be written :$r\_\; \backslash equiv\; \backslash frac\}\; =\; \backslash frac/\backslash langle\; k\; \backslash rangle\; N$ is the probability that a randomly picked edge will connect on one side a vertex with degree $k$ with a vertex of degree $k\text{'}$. To be in the physical region, $r\_\; \backslash leq\; 1$ must be satisfied. The structural cut-off $k\_s$ is then defined by $r\_\; =\; 1$. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Structural cut-off」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
