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).
