This page is a dire page and is in desperate need of an update.
Notes
See
- Notes:Advanced_Linear_Algebra_-_Roman/Chapter_2#Theorem_2.3:_equivalent_statements_to_a_linear_map_being_surjective_.2F_injective
- A linear map is injective if and only if the image of every non-zero vector is a non-zero vector
Some redirects are needed and whatnot.
