Casimir Effect in the Rainbow Einstein's Universe
In the present paper we investigate the effects caused by the modification of
the dispersion relation obtained by solving the Klein-Gordon equation in the
closed Einstein's universe in the context of rainbow's gravity models. Thus, we
analyse how the quantum vacuum fluctuations of the scalar field are modified
when compared with the results obtained in the usual General Relativity
scenario. The regularization, and consequently the renormalization, of the
vacuum energy is performed adopting the Epstein-Hurwitz and Riemann's zeta
functions.Comment: 15 pages, 1 figure. To appear in Europhysics Letter

Umbilicity of constant mean curvature hypersurfaces into space forms
In this paper we establish conditions on the length of the traceless part of
the second fundamental form of a complete constant mean curvature hypersurface
immersed in a space of constant sectional curvature in order to show that it is
totally umbilical.Comment: 14 pages, comments welcom
