Chromatic numbers and products

TL;DR: It is shown that f(n)>=n/2, which is the smallest number so that there are two n chromatic graphs whose product has chromatic number f( n).

The Urysohn sphere is oscillation stable

TL;DR: In this article, the oscillation stability problem for the Urysohn sphere was solved by solving a purely combinatorial problem involving a family of countable homogeneous metric spaces with finitely many distances.
Journal ArticleDOI

The quasi order of graphs on an ordinal

TL;DR: This work introduces a quasi order on the @a-colorings (graphs) by setting f@?g if and only if there is an order-preserving mapping t:@a->@a such that f({@c,@d})=g({ t(@c),t(@d)}) for all @?[@a]^2.

Heyting Algebras and Formal Languages

TL;DR: By introducing a new operation, the exponentiation of formal languages, it turns out that some well known families of languages are closed under this exponentiation, e.

Finite induced graph Ramsey theory: on partitions of subgraphs

TL;DR: The set of graphs G for which there exists an F satisfying F → ( G ) P 2 2 ( P 2 is a path on three vertices) is found to be the union of the set of chordal comparability graphs together with the setof convex graphs.
