It seems to be more of a conceptual problem than anything, but I was wondering, if a manifold $M$ can be locally parametrized (homeomorphic) by a coordinate chart $F:(u_1,....,u_n) \rightarrow p \in M$, can the manifold have dimension greater than $n$? Also why is it that the manifold has dimension $n?$
I would appreciate some clear clarification.
The dimension is the dimension of the space in which the local parametrization is defined, and the dimension cannot be greater.
