چکیده

The projective full embeddings of partial geometries are known. So are the projective full embeddings of semipartial and dual semipartial geometries in case of a > 1. If a 1⁄4 1, a semipartial geometry is known as a partial quadrangle. No projective full embedding of a proper partial quadrangle is known. However besides a unique example for q 1⁄4 2, there is one example known of a dual partial quadrangle fully embedded in a PGð3; qÞ, any q. In this paper we will prove that if the dual of a proper partial quadrangle S is fully embedded in PGð3; qÞ, then mc q q tþ1 . If equality holds, then S is uniquely defined.

A Construction of Extended Generalized Quadrangles Using the Veronesean

Given a finite generalized quadrangle Q, an extended generalized quadrangle is called an extension of Q if each point-residue is isomorphic to Q. There are several known examples of extended generalized quadrangles [4, §1.1], among which those admitting flag-transitive automorphism groups have been extensively studied in their close relations with group theory. Those flag-transitive geometries ...

Small weight codewords in LDPC codes defined by (dual) classical generalized quadrangles

We find lower bounds on the minimum distance and characterize codewords of small weight in low-density parity check codes defined by (dual) classical generalized quadrangles. We analyze the geometry of the non-singular parabolic quadric in PG(4, q) to find information about the low-density parity check codes defined by Q(4, q), W(q) and H(3, q). ForW(q) and H(3, q), we are able to describe smal...

Spreads and ovoids of finite generalized quadrangles

We survey recent results on spreads and ovoids of finite generalized quadrangles. Included in the survey are results on ovoids of PG(3, q); translation ovoids of Q(4, q); characterisations of generalized quadrangles using subquadrangles and ovoids of subquadrangles; and spreads of T2(Ω).

Maximal partial line spreads of non-singular quadrics

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 pa...

Generalized Quadrangles Weakly Embedded of Degree 2 in Projective Space

In this paper, we classify all generalized quadrangles weakly embedded of degree 2 in projective space. More exactly, given a (possibly infinite) generalized quadrangle Γ = (P,L, I ) and a map π from P (respectively L) to the set of points (respectively lines) of a projective space PG(V ), V a vector space over some skew field (not necessarily finite-dimensional), such that: (i) π is injective ...
