I have been using Axler's "Linear Algebra Done Right." In fact I have recommended it here often.
I was wondering if there is a text at that level or higher that uses "kernel" rather than "null space"? And that does not go so far out of it's way to avoid matrices.
Thanks.
There is A Terse Introduction of Linear Algebra, which rapidly overview the subject matter of a typical first course in an elegant way. Particularly, it does prefer the kernels over the null space. A free and legal draft of this book is available at here.
