On the weakest resource for coordination in AV-MACs with conferencing encoders

If the senders and the receiver of an Arbitrarily Varying Multiple-Access Channel (AV-MAC) have access to the outputs of discrete correlated memoryless sources, the same rate region is achievable as if common randomness were available. This reduces the necessary amount of cooperation in an AV-MAC considerably. Moreover, to transmit blocklength-n words, no more than order log n source outputs are required.
