Asymptotic solution for a new class of forbidden r-graphs. (English) Zbl 0732.05031
Summary: We consider the problem of finding ex(n;G), defined as the maximal number of edges an r-graph on n vertices can have that contains no subgraph isomorphic to G. We construct certain r-graphs G for which we find the coefficient $$\tau$$ (G) of the asymptotic expansion $$ex(n;G)=(\tau (G)+o(1))\left( \begin{matrix} n\\ r\end{matrix} \right)$$ as $$n\to \infty$$.
