✦ Synopsis


It is proved that for any rectangle T and for any 2-coloring of the points of the 5dimensional Euclidean space, one can always find a rectangle T' congruent to T , all of whose vertices are of the same color. We also show that for any k-coloring of the k2 + o(k2)-dimensional space, there is a monochromatic rectangle congruent to any given rectangle.

## Abstract For any graph __G__, let __i__(__G__) and μ;(__G__) denote the smallest number of vertices in a maximal independent set and maximal clique, respectively. For positive integers __m__ and __n__, the lower Ramsey number __s__(__m, n__) is the largest integer __p__ so that every graph of or

We prove that for every fixed k and ≥ 5 and for sufficiently large n, every edge coloring of the hypercube Q n with k colors contains a monochromatic cycle of length 2 . This answers an open question of Chung. Our techniques provide also a characterization of all subgraphs H of the hypercube which a

## Abstract We consider the following question: how large does __n__ have to be to guarantee that in any two‐coloring of the edges of the complete graph __K__~__n,n__~ there is a monochromatic __K__~__k,k__~? In the late 1970s, Irving showed that it was sufficient, for __k__ large, that __n__ ≥ 2^_
