Query: Affine Self-similar solutions of the affine curve shortening flow I: The
  degenerate case   In this paper, we consider affine self-similar solutions for the affine curve
shortening flow in the Euclidean plane. We obtain the equations of all affine
self-similar solutions up to affine transformations and solve the equations or
give descriptions of the solutions for the degenerate case. Some new special
solutions for the affine curve shortening flow are found.
