Abstract

This paper explores the issue of identifying rainbow embeddings within random graphs, which occur when all the edges of a subgraph are colored distinctly. Using probabilistic methods, we investigate the conditions under which a random graph contains such an embedding. Specifically, for a specified graph H, when p is greater than the threshold, randomly select a color from the set of colors c to color the edges of graph G, then with high probability graph G contains a rainbow copy of H. These results provide new insights into the interplay between random graph theory and edge coloring, with potential applications in areas such as network design and combinatorics.
