Give two examples where if fn does not converge to f uniformly
on E, but does converge to f pointwise on E, then the following two
theorems do not hold. Write clearly and explain and proof your
claims.
711 Theorem Suppose fn→f uniformly on a set E in a metric space. Let x be a limit point of E, and suppose that (15) Then (A,) converges, and (16) lim f()im A In other words, the conclusion is that lim...
