Projective planes over quadratic 2-dimensional algebras
The split version of the Freudenthal-Tits magic square stems from Lie theory and constructs a Lie algebra starting from two split composition algebras [5, 20, 21]. The geometries appearing in the second row are Severi varieties [24]. We provide an easy uniform axiomatization of these geometries and related ones, over an arbitrary field. In particular we investigate the entry A2 × A2 in the magi...
متن کاملTransitive projective planes and 2-rank
Suppose that a group G acts transitively on the points of a nonDesarguesian plane, P. We prove first that the Sylow 2-subgroups of G are cyclic or generalized quaternion. We also prove that P must admit an odd order automorphism group which acts transitively on the set of points of P. 1 MSC(2000): 20B25, 51A35.
متن کاملKoszul Algebras and Sheaves over Projective Space
We are going to show that the sheafication of graded Koszul modules KΓ over Γn = K [x0, x1...xn] form an important subcategory ∧ KΓ of the coherents sheaves on projective space, Coh(P n). One reason is that any coherent sheave over P n belongs to ∧ KΓup to shift. More importantly, the category KΓ allows a concept of almost split sequence obtained by exploiting Koszul duality between graded Kosz...
متن کاملNew arcs in projective Hjelmslev planes over Galois rings
It is known that some good linear codes over a finite ring (R-linear codes) arise from interesting point constellations in certain projective geometries. For example, the expurgated Nordstrom-Robinson code, a nonlinear binary [14, 6, 6]-code which has higher minimum distance than any linear binary [14, 6]-code, can be constructed from a maximal 2-arc in the projective Hjelmslev plane over Z4. W...
متن کامل16 - dimensional compact projective planes with 3 fixed points
Let P 1⁄4 ðP;LÞ be a topological projective plane with a compact point set P of finite (covering) dimension d 1⁄4 dimP > 0. A systematic treatment of such planes can be found in the book Compact Projective Planes [15]. Each line L A L is homotopy equivalent to a sphere Sl with l j 8, and d 1⁄4 2l, see [15] (54.11). In all known examples, L is in fact homeomorphic to Sl. Taken with the compact-o...
