Higher-Order Deformations, can track the deformations explicitly and show that they are unobstructed. In Section 11 we show how an obstruction theory affects the local ring of the corresponding para-meter space, and in Section 12 we apply this to prove a classical bound on the dimension of the Hilbert scheme of curves in P..
