Quantum Deformation of Relativistic Symmetries: Some Recent Developments

Abstract

Firstly we discuss different versions of noncommutative space-time and corresponding appearance of quantum space-time groups. Further we consider the relation between quantum deformations of relativistic symmetries and so-called doubly special relativity (DSR) theories.Comment: LaTeX, 9 pages.
