Homework Statement
I'm writing a proof for my Real Analysis III class, and in one clause I claim that the intersection of my countably infinite set of intervals {En} where En=(1+1/2+1/3+1/4+...+1/n , ∞), has the property that the infinite intersection of all En's equals ∅ (This would be a lot easier to explain if I finally took the time to learn Latek).
Homework Equations
Not many.
The Attempt at a Solution
Obviously, since ∑1/k ---> ∞, my intersection of my set of intervals gets infinitely smaller in length, ultimately approaching (∞, ∞)=∅. I'd like someone to explain this in formal topological language since I'm not taking another topology class this summer.
