“…As a continuation of the presented work, we are planning to analyse in more detail in the following papers the internal part of the motion for which the second of the solutions in (65), (67), and (68) are expressed with the help of incomplete elliptic integrals and Jacobi elliptic functions, as well as consider the motion of incompressible test bodies on different and more irregular two-dimensional surfaces embedded into the three-dimensional Euclidean space, for example, other (apart from spheres) Delaunay and minimal surfaces of constant (including zero) mean curvature (cylinders, catenoids, helicoids, unduloids, nodoids, gyroids, etc), other (apart from spheres) algebraic surfaces of the second and fourth orders (ellipsoids, pseudo-spheres, tori, etc), or quite specific but very interesting from the geometrical point of view surface which is called the Mylar balloon. 12,16,17…”
