On birational properties of smooth codimension two determinantal varieties
We show that a smooth arithmetically Cohen-Macaulay variety X, of codimension 2 in ސ n if 3 ≤ n ≤ 5 and general if n > 3, admits a morphism onto a hypersurface of degree (n + 1) in ސ n-1 with, at worst, double points; moreover, this morphism comes …
