Shalyt-Margolin, Alexander E. Entropy in the present and early Universe. (English) Zbl 1274.85010 Symmetry Cult. Sci. 18, No. 4, 299-320 (2007). Summary: This is a short analysis of the changes in the concept of entropy as applied to physics of the present-day and early Universe. Of special interest is a leading role of such a notion as deformation of a physical theory. The relation to a symmetry of the corresponding theory is noted. As this work is not a survey, the relevant authors’ works are mainly considered.
