Abstract :
We consider network coding rates for directed and undirected k-pairs networks. For directed networks, meagerness is known to be an upper bound on network coding rates. We show that network coding rate can be ominus(|V|) multiplicative factor smaller than meagerness. For the undirected case, we show some progress in the direction of the k-pairs conjecture.
