We study norms and quasi-norms having large groups of isometries (uniquely maximal and almost transitive). It is shown that a uniquely maximal norm on a Banach space is its 'best' equivalent norm with ...

Types of relations: reflexive, symmetric, transitive and equivalence relations. One to one and onto functions, composite functions, inverse of a function. Binary ...
