We derive local estimates for complete noncompact translating solitons of the Gauss curvature flow in which are graphs over a convex domain . This is closely is related to deriving local estimates for the degenerate Monge–Ampère equation. As a result, given a weakly convex bounded domain , we establish the existence of a translating soliton. In particular, when the boundary has line segments, we show the existence of flat sides of the translator from a local a priori nondegeneracy estimate near the free boundary.
