Maximal partial line spreads of non-singular quadrics
نویسندگان
چکیده
For n ≥ 9, we construct maximal partial line spreads for non-singular quadrics of PG(n, q) for every size between approximately (cn + d)(qn−3 + qn−5) log 2q and qn−2, for some small constants c and d. These results are similar to spectrum results on maximal partial line spreads in finite projective spaces by Heden, and by Gács and Szőnyi. These results also extend spectrum results on maximal partial line spreads in the finite generalized quadrangles W3(q) and Q(4, q) by Pepe, Rößing and Storme.

Partial ovoids and partial spreads of classical finite polar spaces
We survey the main results on ovoids and spreads, large maximal partial ovoids and large maximal partial spreads, and on small maximal partial ovoids and small maximal partial spreads in classical finite polar spaces. We also discuss the main results on the spectrum problem on maximal partial ovoids and maximal partial spreads in classical finite polar spaces. 1 Classical finite polar spaces Th...
متن کاملA NEW METHOD OF CONSTRUCTING MAXIMAL PARTIAL SPREADS OF PG(3, q), MAPPING PG(3, q) OVER A NON-SINGULAR QUADRIC Q(4, q) OF PG(4, q)
We transfer the whole geometry of PG (3, q) over a non-singular quadric Q(4, q) of PG (4, q) mapping suitably PG (3, q) over Q(4, q). More precisely the points of PG (3, q) are the lines of Q(4, q); the lines of PG (3, q) are the tangent cones of Q(4, q) and the reguli of the hyperbolic quadrics hyperplane section of Q(4, q). A plane of PG (3, q) is the set of lines of Q(4, q) meeting a fixed l...

We generalise the definition and many properties of partial flocks of non-singular quadrics in PG(3, q) to partial flocks of non-singular quadrics in PG(2r + 1, q).
متن کاملOn the incidence structures of polar spaces and quadrics
In 1969 Buekenhout characterized non-singular quadrics of finite-dimensional projective spaces as polar spaces spanning the whole space and containing every line of the projective space which they intersect in at least three points (see [2]). Using suitable synthetic properties of the pairs of non-collinear disjoint lines, in this paper I present a new characterization of polar spaces and a com...
متن کاملON THE SPLITTING OF QUASILINEAR p-FORMS
We study the splitting behaviour of quasilinear p-forms in the spirit of the theory of non-singular quadratic forms over fields of characteristic different from 2 using an analogue of Knebusch’s generic splitting tower. Several new applications to the theory of quasilinear quadratic forms are given. Among them, we can mention an algebraic analogue of Vishik’s theorem on ‘outer excellent connect...
