On some extremal problems in graph theory

WebSince the seminal work of Tur ́an, the forbidden subgraph problem has been among the central questions in extremal graph theory. Let ex(n;F) be the smallest number m such that any graph on n vertices with m edges contains F as a subgraph. Then the forbidden subgraph problem asks to find ex(n; F ) for various graphs F . The question can be … WebZbl 477.05049 • Erdös, Paul , Some new problems and results in graph theory and other branches of combinatorial mathematics., Combinatorics and graph theory, Proc.
