The new surfaces are invariant with respect to the composition of rotation and dilatation. The solutions are obtained in closed form %through the Legendre transformation and their asymptotic behaviour is described.19 pages, 3 figuresDifferential GeometryClassical Analysis and ODEs35C20, 49Q05, 53A10, 85A15text
