On multiples of divisors associated to Veronese embeddings with defective secant variety
Abstract
In this note we consider multiples aD, where D is a divisor of the blowup of Pn along points in general position which appears in the Alexander and Hirschowitz list of Veronese embeddings having defective secant varieties. In particular we show that there is such a D with h1 (X, D) > 0 and h1(X, 2D) = 0.
