We classify the translators to the flows by sub-affine-critical powers of Gauss curvature. This corresponds to the classification of entire solutions to degenerate Monge-Ampere equation detD2u=(1+|Du|2)212α on R2 for 0<α<1/4. For the affine-critical-case detD2u=1, the classical result by Jorgens, Calabi and Pogorelov shows every solution must be a convex paraboloid and hence the level sets are homothetic ellipses. In our case, the level sets of given solution converge to a circle or a curve with k-fold symmetry for some k>2. These curves are closed shrinking curves to the α1α-curve shortening flow, classified by B. Andrews in 2003. This is a joint work with K. Choi and S. Kim.
