Webis zero, or is the weighted Shapley value of a linear combination of unanimity games, (N ∪ γ, u {T, η}) such that l belongs to η in all of them. If the difference is zero, the result is trivial. In another case, taking into account that the weighted Shapley value of each player or link is proportional to his, her or its weight, we have Webpi.shapley Power based on the Shapley-Shubik index. Description This function determines the distribution of the power based on the Shapley-Shubik index and the Owen value.
