This is a summary of lectures in superstring cosmology given by the author at the CORFU 2009 School and Workshops “Theory – Cosmology – Phenomenology”, Corfu Institute, Greece, Sept. 6.–13, 2009. These lectures are based on some recent developments and ideas, in the framework of superstring theory, concerning the evolution and structure of the universe in (i) the very early “non‐geometric” cosmological era, (ii) the intermediate “radiation‐like” era and (iii) the late time cosmological era… Expand

The thermodynamics of superstring theories (SST-I, SST-II and heterotic string theory) and its application to the cosmology are studied. The free energy of superstring gas is calculated in the… Expand

In this work, we review the results of Refs [1]-[5] dedicated to the description of the early Universe cosmology induced by quantum and thermal effects in superstring theories. The present evolution… Expand

We study the cosmology of perturbative heterotic superstring theory during the radiation‐like era for semi‐realistic backgrounds with initial 𝒩 = 1 supersymmetry. This analysis is valid for times… Expand

We consider four dimensional heterotic string backgrounds for which supersymmetry is spontaneously broken via the Scherk‐Schwarz mechanism on an internal spatial cycle and by finite temperature… Expand
