Metric Spaces and their Groups,f a few reasonablelooking properties, or axioms, and the result is called a metric on that space. Having defined a structure such as this on a set, it is natural to study those transformations, or maps, of such sets which preserve that structure. The requirement that these maps be invertible then leads naturally into the theory of groups.
