Abstract

Let vd(P2)OP2(d)v_d(\mathbb{P}^2)\subset |\mathcal{O}_{\mathbb{P}^2}(d)| denote the dd-uple Veronese surface. After studying some general aspects of the wall-crossing phenomena for stability conditions on surfaces, we are able to describe a sequence of flips of the secant varieties of vd(P2)v_d(\mathbb{P}^2) by embedding the blow-up \mboxblvd(P2)OP2(d)\mbox{bl}_{v_d(\mathbb{P}^2)}|\mathcal{O}_{\mathbb{P}^2}(d)| into a suitable moduli space of Bridgeland semistable objects on P2\mathbb{P}^2.
