On the independence number of graphs related to a polarity [PDF]
Journal of Graph Theory, 2018 AbstractWe investigate the independence number of two graphs constructed from a polarity of . For the first graph under consideration, the Erdős‐Rényi graph , we provide an improvement on the known lower bounds on its independence number. In the second part of the paper, we consider the Erdős‐Rényi hypergraph of triangles .
