Abstract

For natural numbers n, k, r and s there exists a complete tree ? of height and arity\(r^{\left( {\mathop {K + 1}\limits_s } \right)} (n - 1) + 1\) such that for an arbitrary r-colouring of the s-chains of T a level-preserving monochromatically embedded copy of a complete tree of height k and arity n can be found in T. Moreover, a best possible upper bound for K is given.
