Curve Shortening Flow and Smooth Projective Planes

Abstract

In this paper, we study a family of curves on $S^2$ that defines a two-dimensional smooth projective plane. We use curve shortening flow to prove that any two-dimensional smooth projective plane can be smoothly deformed through a family of smooth projective planes into one which is isomorphic to the real projective plane. In addition, as a consequence of our main result, we show that any two smooth embedded curves on $R{P}^2$ which intersect transversally at exactly one point converge to two different geodesics under the flow.
