pg (n,q)中的一维对偶弧是投影平面中对偶弧的高维模拟。对于除2以外的每一个素数幂,在pg (n,q)中存在一定大小的加维对偶弧(d≥2)意味着≤d(d+ 3)/2(定理1)。这是最好的可能,因为最近在pg (d(d+ 3)/2,q)中构造了尺寸为∑d−1i=0qi的d维对偶弧,使用了首先由Thas和van Maldeghem观察到的Veronesean(命题7)。也给出了另一种使用帽的结构(提案10)。
Ad-dimensional dual arc inPG(n,q) is a higher dimensional analogue of a dual arc in a projective plane. For every prime powerqother than 2, the existence of ad-dimensional dual arc (d≥ 2) inPG(n,q) of a certain size impliesn≤d(d+ 3)/2 (Theorem 1). This is best possible, because of the recent construction ofd-dimensional dual arcs inPG(d(d+ 3)/2,q) of size ∑d−1i=0qi, using the Veronesean, observed first by Thas and van Maldeghem (Proposition 7). Another construction using caps is given as well (Proposition 10).
