Suppose K is compact and fn is a sequence of continuous functions on K which converges pointwisely to a continuous function f(x), and fn(x)≥fn+1(x) for all x ∈ K and n ∈ N. Show fn→f uniformly.
My thoughts:
To prove uniform convergence I think we should use the definition(epsilon delta). But I'm not sure how to use other conditions. I was trying to combine "uniform
continuous" and "pointwise convergence" but it didn't work.
Answer
Actually, this is the Dini’s Theorem. You can see this lecture note: http://www.math.ubc.ca/~feldman/m321/dini.pdf
