Inherited unitals in Moulton planes [Elektronski vir]Korchmáros, Gábor ; Sonnino, Angelo ; Szőnyi, TamásWe prove that every Moulton plane of odd order-by duality every generalised André plane-contains a unital. We conjecture that such unitals are non-classical, that is, they are not isomorphic, as ... designs, to the Hermitian unital. We prove our conjecture for Moulton planes which differ from PG(2, q2) by a relatively small number of point-line incidences. Up to duality, our results extend previous analogous results-due to Barwick and Grünin-concerning inherited unitals in Hall planes.Source: Ars mathematica contemporanea [Elektronski vir]. - ISSN 1855-3974 (Vol. 14, no. 2, 2018, str. 251-265)Type of material - e-article ; adult, seriousPublish date - 2018Language - englishCOBISS.SI-ID - 1540928452
