On the automorphism groups of Dowling geometries

Gary K. Schwartz

Research output: Contribution to journalArticlepeer-review


In 'Automorphisms of Dowling lattices and related geometries', J. Bonin constructed the automorphism group A of a Dowling lattice as the image of a certain semidirect product, A = θ(K ⋊ H). In this work we find necessary and sufficient conditions for this quotient to be the semidirect product A = θ(K) ⋊ θ(H). In addition, we include a construction of A that lends itself to computation more readily than that found in Bonin's work.
