yet his mathematics is still as fresh as when he did it. Primarily this is because Tura n frequently looked at problems from a new point of view. I have heard this expressed by those who knew his work in areas I know well as well as in areas I do not understand at all. This often means that it will

✦ Synopsis
A probability measure s on the unit circle T is called a Tura´n measure if any point of the open unit disc D is a limit point of zeros of the orthogonal polynomials associated to s: We show that many classes of measures, including Szego¨measures, measures with absolutely convergent series of their parameters, absolutely continuous measures with smooth densities, contain Tura´n measures.

## Abstract A ρ‐mean coloring of a graph is a coloring of the edges such that the average number of colors incident with each vertex is at most ρ. For a graph __H__ and for ρ ≥ 1, the __mean Ramsey–Turán number RT__(__n, H,ρ − mean__) is the maximum number of edges a ρ‐__mean__ colored graph with _
The maximum number of edges in a graph with no constant degree clique of a fixed size is determined asymptotically.
A system of r-element subsets (blocks) of an n-element set X n is called a Tura n (n, k, r)-system if every k-element subset of X n contains at least one of the blocks. The Tura n number T(n, k, r) is the minimum size of such a system. We prove upper estimates: + as n Ä , r Ä , k=(#+o(1))r, #>1.
