The paper deals with common generalizations of classical results of Ramsey and Turán. The following is one of the main results. Assumek≧2, ε>0,Gn is a sequence of graphs ofn-vertices and at least 1/2((3k−5) / (3k−2)+ε)n2 edges, and the size of the largest independent set inGn iso(n). LetH be any graph of arboricity at mostk. Then there exists ann0 such that allGn withn>n0 contain a copy ofH. This result is best possible in caseH=K2k.
