摘要

Given a hereditary family g of admissible graphs and a function lambda(G) that linearly depends on the statistics of order-k subgraphs in a graph G, we consider the extremal problem of determining lambda(n, g), the maximum of lambda(G) over all admissible graphs G of order n. We call the problem perfectly B-stable for a graph B if there is a constant C such that every admissible graph G of order n = C can be made into a blow-up of B by changing at most C(lambda(n, g) - lambda(G)) (n 2) adjacencies. As special cases, this property describes all almost extremal graphs of order n within o(n(2)) edges and shows that every extremal graph of order n = C is a blow-up of B.
