Abstract

We are given a bipartite graph that contains at least one perfect matching and where each edge is colored from a set Q=\{c_1,c_2,\ldots,c_q}\. Let Qi={eE(G):c(e)=ci}Q_i=\set{e\in E(G):c(e)=c_i}, where c(e)c(e) denotes the color of ee. The perfect matching color profile mcp(G)mcp(G) is defined to be the set of vectors (m1,m2,,mq)[n]q(m_1,m_2,\ldots,m_q)\in [n]^q such that there exists a perfect matching MM such that MQi=mi|M\cap Q_i|=m_i. We give bounds on the matching color profile for a randomly colored random bipartite graph.
