diffeology (複数形 diffeologies)

1. (differential geometry) The set of smooth parametrizations of a given set ${\displaystyle X}$; the set of smooth maps ${\displaystyle S\rightarrow X}$, where ${\displaystyle S}$ is any open set ${\displaystyle \subseteq \mathbb {R} ^{n}}$; the theory of such constructs.

     In this case, ${\displaystyle A}$ and ${\displaystyle f(A)}$ are both D-open and ${\displaystyle f:A\rightarrow f(A)}$ is a diffeomorphism where ${\displaystyle A}$ and ${\displaystyle f(A)}$ are equipped with their subset diffeology.
