### Is a diffeomorphism a bijection?

**Is the restriction of a diffeomorphism a diffeomorphism?**

is a diffeomorphism.

**What is Matrix Lie group?**

A matrix Lie group is a subgroup G ⊆ GL(n) with the following prop- erty: If {Ak} is a convergent sequence in G, Ak → A for some A ∈ gl(n), then either. A ∈ G, or A is not invertible. Remark 4.2. An equivalent way of definiting matrix Lie groups is to define them as closed subgroups of GL(n).
