A hole in a graph is an induced cycle on at least four vertices. A graph is Berge if it has no odd hole and if its … saying that every Berge graph either is in a well understood basic class or has some kind of decomposition. Then, Chudnovsky …

Our first model for the evolution of a dynamic portfolio is a random walk on the graph corresponding to the … investment policy chosen. Next, using graph theory and quantum probability, we compute the probabilities for a dynamic portfolio …

In this paper we … are able to deal with this case by a clever combination of notions from different fields, such as relational algebra, graph … of relations allows to deal with graph sizes that are sufficient for practical applications of coalition formation. …
