摘要
Kinematics of moving curves in two dimensions is formulated in terms of intrinsic geometries. The velocity is assumed to be local in the sense that it is a functional of the curvature and its derivatives. The modified Korteweg-de Vries (mKdV) equation and its hierarchy are included in the theory when the normal velocity obeys a recursion relation. Curves corresponding to solutions of the mKdV equation are explicitly constructed.
