In this paper we will analyze the Fantappì e group and its properties in connection with Cantorian space-time. Our attention will be focused on the possibility of extending special relativity. The cosmological consequences of such extension appear relevant , since thanks to the Fantappì e group , the model of the Big Bang and that of stationary state become(More)
We study the final/initial behavior of a dust Universe with spatial spherical symmetry. This study is done in proximity of the col-lapse/generation times by an expansion in fractional Puiseux series. Even if the evolution of the universe has different behaviours depending on the initial data (in particular on the initial spatial curvature), we show that, in(More)
