Editing Differential structure (section)

{{Short description|Mathematical structure}}
In [[mathematics]], an ''n''-[[Dimension (mathematics and physics)|dimensional]] '''differential structure''' (or '''differentiable structure''') on a [[Set (mathematics)|set]] ''M'' makes ''M'' into an ''n''-dimensional [[differential manifold]], which is a [[topological manifold]] with some additional structure that allows for [[differential calculus]] on the manifold. If ''M'' is already a topological manifold, it is required that the new topology be identical to the existing one.
