Three decades ago Heath found the integral form of the exact analytic growing mode solution of the linear density perturbation δ on sub-horizon scales including the cosmological constant or the curvature term. Recently, we obtained the exact analytic form of this solution in our previous work [1]. Interestingly, we are able to extend this solution for general dark energy models with the constan...

La mision Solar Orbiter intentara responder a cuatro de las cuestiones mas relevantes la actual fisica solar y heliofisica, entre cuales siguiente sera especial relevancia para el trabajo que aqui se presenta: impulsa viento donde origina campo magnetico corona?. De esta pregunta global, surgen otras dos detalladas: son los mecanismos calientan corona aceleran solar? fuentes turbulencia en como...

We study a recurrence relation, where the generating function, as a formal power series, satisfies a differential equation that can be solved in a suitable domain; this yields an analytic function in a domain, but the solution is singular at the origin and the generating function has radius of convergence 0. Nevertheless, the solution to the recurrence can be obtained from the analytic solution...
