本文研究了Ak-点图G作为n-点图的导出子图出现的最大数目,当这个数目被表示为所有k-点导出子图的分数时,它趋向于一个确定的极限为N,≥,→∞。这个极限,我们称之为G的可归纳性,是G的一个有效的可计算不变量。我们研究了这个不变量的基本性质:它与图上的各种运算的关系,它的最大值和最小值,以及它对某些特定图的值。
We investigate the maximum number of ways in which ak-vertex graphGcan appear as an induced subgraph of ann-vertex graph, forn≥k. When this number is expressed as a fraction of allk-vertex induced subgraphs, it tends to a definite limit asn→ ∞. This limit, which we call theinducibilityofG, is an effectively computable invariant ofG. We examine the elementary properties of this invariant: its relationship to various operations on graphs, its maximum and minimum values, and its value for some particular graphs.
