I'm going to find some Exercise books in linear algebra and I was wondering if there are some exercise books (that is, books with solved problems and exercises) The books I'm searching for should be:
- full of hard, non-obvious, non-common, and thought-provoking problems;
- rich of complete, step by step, rigorous, and enlightening solutions;
Thanks in advance
The book you are looking for is Problems and Theorems in Linear Algebra (Translations of Mathematical Monographs, Vol. 134) Paperback – June 13, 1994 by V. V. Prasolov. There is much fuller second edition, but as far as I know it was not translated (yet) into English.
