چکیده

SDPS-sets are very nice sets of points in dual polar spaces which themselves carry the structure of dual polar spaces. They were introduced in [8] because they gave rise to new valuations and hyperplanes of dual polar spaces. In the present paper, we show that the symplectic dual polar space DW (4n− 1, q), n ≥ 2, has up to isomorphisms a unique SDPS-set.

The uniqueness of the SDPS-set of the symplectic dual polar space DW(4n-1, q), n>=2

SDPS-sets are very nice sets of points in dual polar spaces which themselves carry the structure of dual polar spaces. They were introduced in [8] because they gave rise to new valuations and hyperplanes of dual polar spaces. In the present paper, we show that the symplectic dual polar space DW (4n− 1, q), n ≥ 2, has up to isomorphisms a unique SDPS-set.

Generating Symplectic and Hermitian Dual Polar Spaces over Arbitrary Fields Nonisomorphic to F2

Cooperstein [6], [7] proved that every finite symplectic dual polar space DW (2n− 1, q), q 6= 2, can be generated by ( 2n n ) − ( 2n n−2 ) points and that every finite Hermitian dual polar space DH(2n − 1, q2), q 6= 2, can be generated by (2n n ) points. In the present paper, we show that these conclusions remain valid for symplectic and Hermitian dual polar spaces over infinite fields. A conse...

3 DW ( 2 n , q ) , n ≥ 3 , has no ovoid : A single proof

An ovoid of a dual polar space ∆ is a point set meeting every line of ∆ in exactly one point. For the symplectic dual polar space DW (6, q), Cooperstein and Pasini [2] have recently proved no ovoid exists if q is odd. Earlier, Shult has proved the same for even q (cf. [3, 2.8]). In this paper, we prove the non-existence of ovoids in DW (6, q) independently from the parity of q. MSC 2000: 51A15,...

On isometric full embeddings of symplectic dual polar spaces into Hermitian dual polar spaces

Let n ≥ 2, let K,K′ be fields such that K′ is a quadratic Galoisextension of K and let θ denote the unique nontrivial element in Gal(K′/K). Suppose the symplectic dual polar space DW (2n− 1,K) is fully and isometrically embedded into the Hermitian dual polar space DH(2n − 1,K′, θ). We prove that the projective embedding of DW (2n − 1,K) induced by the Grassmann-embedding of DH(2n − 1,K′, θ) is ...

Hyperplanes of DW ( 5 , K ) with K a perfect field of characteristic 2 Bart

Let K be a perfect field of characteristic 2. In this paper, we classify all hyperplanes of the symplectic dual polar space DW (5,K) that arise from its Grassmann embedding. We show that the number of isomorphism classes of such hyperplanes is equal to 5 + N , where N is the number of equivalence classes of the following equivalence relation R on the set {λ ∈ K |X2 + λX + 1 is irreducible in K[...
