Let G be a 2-connected weighted graph and k ≥ 2 an integer. In this note we prove that if the sum of the weighted degrees of every k + 1 pairwise nonadjacent vertices is at least m, then G contains either a cycle of weight at least 2m/(k + 1) or a spanning tree with no more than k leaves.
This paper puts forward an algorithm that computes the diffusion of events and actions across networks of economic agents, an algorithm that is applicable when such networks can be represented as weighted directed graphs. The functioning of the algorithm is shown in three applications. First, the al
