    Different representations of the Levi-Civita Bertotti Robinson solution 

    Grøn, Øyvind; Johannesen, Steinar (Springer Verlag, 2013-04-23)
    The Levi-Civita Bertotti Robinson (LBR) spacetime is investigated in various coordinate systems. By means of a general formalism for constructing coordinates in conformally flat spacetimes, coordinate transformations ...

    The Cosmic Causal Mass 

    Bræck, Simen; Grøn, Øyvind; Farup, Ivar (MDPI, 2017)
    In order to provide a better understanding of rotating universe models, and in particular the Gödel universe, we discuss the relationship between cosmic rotation and perfect inertial dragging. In this connection, the concept ...

    Warm inflation 

    Grøn, Øyvind (MDPI, 2016)
    I show here that there are some interesting differences between the predictions of warm and cold inflation models focusing in particular upon the scalar spectral index ns and the tensor-to-scalar ratio r. The first thing ...

    The twin paradox and the principle of relativity 

    Grøn, Øyvind (Institute of Physics Publ., 2013-02-14)
    The twin paradox is intimately related to the principle of relativity. Two twins A and B meet, travel away from each other and meet again. From the point of view of A, B is the traveller. Thus, A predicts B to be younger ...

    Predictions of Spectral Parameters by Several Inflationary Universe Models in light of the Planck Results 

    Grøn, Øyvind (MDPI, 2018-01-29)
    I give a review of predictions of values of spectral parameters for a large number of inflationary models. The present review includes detailed deductions and information about the approximations that have been made, written ...
