Abstract: | Nowadays the term monochromatic and heterochromatic (or rainbow, multicolored) subgraphs of an edge-colored graph appeared
frequently in literature, and many results on this topic have been obtained. In this paper, we survey results on this subject.
We classify the results into the following categories: vertex-partitions by monochromatic subgraphs, such as cycles, paths,
trees; vertex partition by some kinds of heterochromatic subgraphs; the computational complexity of these partition problems;
some kinds of large monochromatic and heterochromatic subgraphs. We have to point out that there are a lot of results on Ramsey
type problem of monochromatic and heterochromatic subgraphs. However, it is not our purpose to include them in this survey
because this is slightly different from our topics and also contains too large amount of results to deal with together. There
are also some interesting results on vertex-colored graphs, but we do not include them, either.
