Definition. A metric space is a set X together with a function d (called a metric or distance function) which assigns a real number d (x, y) to every pair x, y X satisfying the properties (or axioms): 1  d (x, y) 0 and d (x, y) = 0 x = y, 2  d (x, y) = d (y, x), 3  d (x, y) + d (y, z) d (x, z).
CHAPTER IVNORMED LINEAR SPACES AND BANACH SPACESDEFINITION A Banach space is a real normed linear space that is acomplete metric space in the metric deï¬ned by its norm. A complexBanach space is a complex normed linear space that is, as a real normedlinear space, a Banach space.X n are normed linear spaces, show that the direct sum ni=1 X i, equipped with the max norm, is a normed linear space. If eachX i is a Banach space, show thatL ni=1 X i is a Banach space.(f) Let X 1 ,...
