Provides a unified, complete, and self-contained exposition of the main algebraic theorems of invariant theory for matrices in a characteristic free approach. More precisely, it contains the description of polynomial functions in several variables on the set of $mtimes m$ matrices with coefficients in an infinite field or even the ring of integers, invariant under simultaneous conjugation.
