Affine Spaces within Projective Spaces

چکیده
We endow the set of complements of a fixed subspace of a projective space with the structure of an affine space, and show that certain lines of such an affine space are affine reguli or cones over affine reguli. Moreover, we apply our concepts to the problem of describing dual spreads. We do not assume that the projective space is finitedimensional or pappian.

Affinization of Segre products of partial linear spaces
Hyperplanes and hyperplane complements in the Segre product of partial linear spaces are investigated. The parallelism of such a complement is characterized in terms of the point-line incidence. Assumptions, under which the automorphisms of the complement are the restrictions of the automorphisms of the ambient space, are given. An affine covering for the Segre product of Veblenian gamma spaces...

متن کاملCombinatorics of Finite Geometries
85 admirably clear. While the book is devoted to a single problem, the techniques employed would seem to have wider utility, and so should appeal to those interested in efficiency of algorithms in graph theory, and further (perhaps) to those wishing to apply such ideas to the real world. I enjoyed reading this book. It is written in a way which should appeal to advanced undergraduate and postgr...
