Abstract : We consider restricted games on weighted communication graphs associated with minimum partitions. We replace in the classical definition of Myerson-s graph-restricted game the connected components of any subgraph by the sub-components corresponding to a minimum partition. This minimum partition P min is induced by the deletion of the minimum weight edges. We provide necessary conditions on the graph edge-weights to have inheritance of convexity from the underlying game to the restricted game associated with P min. Then we establish that these conditions are also sufficient for a weaker condition, called F-convexity, obtained by restriction of convexity to connected subsets. Moreover we show that Myerson-s game associated to a given graph G can be obtained as a particular case of the P min-restricted game for a specific weighted graph G ′. Then we prove that G is cycle-complete if and only if a specific condition on adjacent cycles is satisfied on G ′ .
