MHB Power series and uniform convergence.

Click For Summary
The discussion centers on determining the uniform convergence of the power series (2^n/n)*z^n over the interval [-1/3, 1/3]. The ratio test or root test is suggested as standard methods for assessing convergence. It is noted that if a power series converges on a closed and bounded interval, it also converges uniformly on that interval. Participants are encouraged to apply these tests to the given series. The conclusion emphasizes the importance of these tests in establishing uniform convergence.

Hi.
I have this power serie (2^n/n)*z^n that runs from n=1 to infinity, and I have to show whether it's uniform konvergence on [-1/3, 1/3] or not.

I hope someone can help me with this.

It is fairly standard to use the "ratio test" or "root test" to determine convergence of a power series. And I presume you know that "if a power series converges on a closed and bounded interval, then it converges uniformly there."

We all know the definition of n-dimensional topological manifold uses open sets and homeomorphisms onto the image as open set in ##\mathbb R^n##. It should be possible to reformulate the definition of n-dimensional topological manifold using closed sets on the manifold's topology and on ##\mathbb R^n## ? I'm positive for this. Perhaps the definition of smooth manifold would be problematic, though.
