摘要
We show that if r >= s >= 2, n > r(8), and G is a graph of order n containing as many r-cliques as the r-partite Turan graph of order n, then G has more than n(r-1)/r(2r+12) cliques sharing a common edge unless G is isomorphic to the r-partite Turin graph of order n. This structural result generalizes a previous result that has been useful in extremal graph theory.
