The improved description of the planets’ interior is provided. We examine modified gravity effects on Earth-like planets composed iron core and silicate mantle. confirm that mass–radius relations as well density profiles differ with respect to commonly adopted Newtonian models.
The wave equation ?tt?c2?xu(x,t)=e?tf(x,t) in the cone {(x,t):?x??t,x?Rd,t?R+} is shown to have a unique solution if u and its partial derivatives x are L2(e?t) on cone, can be explicit given Fourier series of orthogonal polynomials cone. This provides particular for boundary value problems non-homogeneous which combined with homogeneous obtain full solution.
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
In this paper, we prove two rigidity results for non-positively curved homogeneous Finsler metrics. Our first main result yields an extension of Hu-Deng's well-known proven the Randers Indeed, that every connected space with non-positive flag curvature and isotropic S-curvature is Riemannian or locally Minkowskian. We extend Szabó's theorem Berwald surfaces show metrics are second to (α,β)-metr...
