The issue of improving the shape of paraboloidal surfaces of transformable reflectors is still considered one of the most challenging problems. In modern transformable reflectors, the paraboloidal shape of the center of deployable reflectors is ensured by placing nodes of a flexible tape grid. It is accepted that the maximum accuracy of the parabolic surface is achieved under conditions of equal loads of the nodes. Changes in the geometry of the paraboloidal surface of the reflectors mainly develop in the peripher...

Recently, Horava-Lifshitz proposed the theory of quantum gravity, which takes into account the degree of renormalizability in the ultraviolet. This was achieved by anisotropic scaling between space and time, and, therefore, it violates the Lorentz invariance in the ultraviolet range. The infrared limit of a theory reproduces the general theory of relativity for a particular choice of parameter, namely . Lorentz symmetry breaking is performed by preferred foliation of threedimensional space-like hypersurfaces, whic...
