Dominance of capacities by k-additive belief functions

Miranda, Pedro; Grabisch, Michel; Gil, Pedro - HAL - 2006

In this paper we deal with the set of $k$-additive belieffunctions dominating a given capacity. We follow the lineintroduced by Chateauneuf and Jaffray for dominating probabilities and continued by Grabisch for general $k$-additive measures.First, we show that the conditions for the general...
