On a Generalized Anti-Ramsey Problem

Combinatorica, 2001
For integers \(p,q_1,q_2 > 0\), a coloring of \(E(K_n)\) is called \((p,q_1,q_2)\)-coloring if at least \(q_1\) and at most \(q_2\) different colors appear at the edges of every \(K_p \subseteq K_n\). \(R(n,p,q_1,q_2)\) denotes the maximum number of colors in a \((p,q_1,q_2)\)-coloring of \(E(K_n)\). The authors prove several bounds, especially for \(R(

Bipartite anti‐Ramsey numbers of cycles

Journal of Graph Theory, 2004
AbstractWe determine the maximum number of colors in a coloring of the edges of Km,n such that every cycle of length 2k contains at least two edges of the same color. One of our main tools is a result on generalized path covers in balanced bipartite graphs.

Local Anti-Ramsey Numbers of Graphs

Combinatorics, Probability and Computing, 2003
A subgraph H in an edge-colouring is properly coloured if incident edges of H are assigned different colours, and H is rainbow if no two edges of H are assigned the same colour. We study properly coloured subgraphs and rainbow subgraphs forced in edge-colourings of complete graphs in which each vertex is incident to a large number of colours.

Rainbow Arithmetic Progressions and Anti-Ramsey Results

Combinatorics, Probability and Computing, 2003
The van der Waerden theorem in Ramsey theory states that, for every k and t and sufficiently large N, every k-colouring of [N] contains a monochromatic arithmetic progression of length t. Motivated by this result, Radoičić conjectured that every equinumerous 3-colouring of [3n] contains a 3-term rainbow arithmetic progression, i.e., an arithmetic ...
