–– Advanced Linear Algebra (Draft) ––

This is a draft of a textbook on advanced linear algebra, meaning it assumes some knowledge of
vector spaces and linear maps.
It is based on the second part of an introductory course given at a German university, and I am
currently busy translating it into English.
The idea is to adapt the textbook to fit the Australian curriculum, which requires reorganising
the text somewhat, as an introductory section on algebraic structures such as groups and rings
needs to be included.
You can download the current draft here.
