Dimitrios Kastrinakis,Yannis Tzitzikasation: what, I ask you, do the terms “geometry” and “light” actually mean to us and how might a causal link, in the sense of the geometry of light — be undertaken, logically and (ideally) entertainingly? Let’s start with the big words: “geometry” and “light.” These are certainly difficult concepts a

Janne Kuuskeri,Tuomas Turtospaces have been used from the very beginning and, after Weyl and Wigner, group representations havecome in conclusively. Recent discoveries seem to indicate that the role of group representations is destined for further expansion, not to speak of the impact of the theory of several complex variable

Roberto Rodríguez-Echeverría,José María Conejero,Marino Linaje,Juan Carlos Preciado,Fernando Sánchezthe simplest possible introduction to fundamentals of modem geometry: curvature, group actions, and covering spaces. 2. The prerequisites are modest and standard. A little linear algebra (mostly 2 x 2 matrices), calculus as far as hyperbolic functions, ba sic group theory (subgroups and cosets), an
