The automorphism group of projective norm graphs

The projective norm graphs are central objects to extremal combinatorics. They appear in a variety of contexts, most importantly they provide tight constructions for the Turán number of complete bipartite graphs K t , s with s > ( t - 1 ) ! . In this note we deepen their understanding further by...

Description
Summary:The projective norm graphs are central objects to extremal combinatorics. They appear in a variety of contexts, most importantly they provide tight constructions for the Turán number of complete bipartite graphs K t , s with s > ( t - 1 ) ! . In this note we deepen their understanding further by determining their automorphism group.
