Notation: In this assignment E denotes a measurable subset of R and L(E) the set eal vector space. For f e L(E) the norm of f is defined as This is a real number (not oo) as f is integrable over E.

Let X be a non-empty set. Show that the only dense subset of X with respect to the discrete metric ddise is X. The whole set of any metric spaces is always dense, so this question is really asking you to exclude all other possibilities. Show that if (X, d) is a metric space and has dense subset A + X, then (X, d) is not topologically equivalent to (X, ddisc). (Note that this is another way of showing that...
