N2 - We consider distributed algorithms for approximate maximum matching on general graphs. Our main result is a randomized (4 + )-approximation distributed algorithm for weighted maximum matching, whose running time is O(log n) for any constant > 0, where n is the number of nodes in the graph. In addition, we consider the dynamic case, where nodes are inserted and deleted one at a time. For unweighted dynamic graphs, we give an algorithm that maintains a (1 + )-approximation in O(1/) time for each node insertion or deletion. For weighted dynamic graphs we give a constant-factor approximation algorithm that runs in constant time for each insertion or deletion.
