How do I determine whether the following sequences of complex functions converge uniformly?

i) z/n

ii)1/nz

iii)nz^2/(z+3in)

where n is natural number

You have to specify on which set you want uniform converge (except if you have to determine the domains of convergence). First, find the pointwise limits.
 
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.
