## Semidefinite approximations for bicliques and biindependent pairs

 We investigate some graph parameters asking to maximize the size of biindependent pairs (A,B) in a bipartite graph G = (V1 \cup V2;E), where A\subseteq V1, B \subseteq V2 and A \cup B is independent. These parameters also allow to study bicliques in general graphs (via bipartite double graphs). When the size is the … Read more
