Abstract

We consider {translators} (i.e., initial condition of translating solitons) to mean curvature flow (MCF) in the hyperbolic 33-space H3\mathbb H^3, providing existence and classification results. More specifically, we show the existence and uniqueness of two distinct one-parameter families of complete rotational translators in H3\mathbb H^3, one containing catenoid-type translators, and the other parabolic cylindrical ones. We establish a tangency principle for translators in H3\mathbb H^3 and apply it to prove that properly immersed translators to MCF in H3\mathbb H^3 are not cylindrically bounded. As a further application of the tangency principle, we prove that any horoconvex translator which is complete or transversal to the x3x_3-axis is necessarily an open set of a horizontal horosphere. In addition, we classify all translators in H3\mathbb H^3 which have constant mean curvature. We also consider rotators (i.e., initial condition of rotating solitons) to MCF in H3\mathbb H^3 and, after classifying the rotators of constant mean curvature, we show that there exists a one-parameter family of complete rotators which are all helicoidal, bringing to the hyperbolic context a distinguished result by Halldorsson, set in R3\mathbb R^3.
