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).
Two Spaces After a Period: A Typographic Tradition. A brief note on terminology: the âdouble spaceâ (no hyphen) requires two consecutive space characters to be struck on a keyboard. The âdouble-spaceâ (with a hyphen), or âwide spaceâ is a single, wide character thatâs more properly referred to as an âemspaceâ like its cousin, the emdash.
