Transitive Deficiency-One Baer Subgeometry Partitions

admitting groups fixing one Baer subgeometry and acting transitively on the remaining Baer subgeometries.  ...  When q is even, we show that a Baer subgeometry partition of PG(2, q 2 ) with a group fixing one and transitive on the remaining PG(2, q)'s forces the partition to be classical or q=4 and the partition  ...  Moreover, we discuss ''transitive'' deficiency one partial Baer subgeometry partitions; deficiency one partial BSG's admitting a group transitive on the subplanes of the partition.  ...

A 98 (2002), no. 1, 127-149.  ...  A Baer subgeometry partition (BSG) of a finite projective space PG(2k,q7) is a partition of its points by Baer subspaces (isomor- phic to PG(2k,q)). The authors refer to a result of N.  ...

We characterize the Miquelian Laguerre planes as those admitting a group containing a non-trivial elation and acting transitively on flags, with an additional hypothesis-a quasiprimitive action on circles  ...  This had a profound effect on the study of geometry, eventually elevating symmetry to a central role.  ...  involution, 28, 98 Baer subgeometry, 97 Baer subplanes, 28 Baer subspaces, 27 base, 47 blank type I, 13 blank type II, 13 block design, 24 block-tactical, 100 Buekenhout-Metz unitals, 29 bundle, 72 bundle  ...
