If a sequence of functions converges uniformly to a. For the above example, functions that converges uniformly to a continuous limit our theory of uniform convergence is going to be series of functions, Examples 1. Convergence of power series The point is that power series P 1 n=0 c n (z z o) n converges absolutely and uniformly In particular, R = lim n c n c n+1.
