Peter Šemrl: From Loewner's characterization of operator monotone functions to the fundamental theorem of chronogeometry

Local order isomorphisms of matrix and operator domains will be discussed. A connection with Loewner's theorem and the fundamental theorem of chronogeometry will be explained. The first one characterizes operator monotone functions while the second one describes the general form of bijective preservers of light-likeness on the classical Minkowski space.
