摘要: Abstract The problem of curve evolution as a function its local geometry arises naturally in many physical applications. A special case this is the shortening which has been extensively studied. Here, we consider general and prove an existence theorem for classical solution. main rests on lemmas that bound length, curvature, how far can travel.
