A Spectral Theory of Noncommuting Operators - Hardcoverby Rongwei Yang (Author) The main goal of this book is to describe various aspects of the theory of joint spectra for matrices and linear operators. It is suitable for a graduate level topic course in spectral theory and or representation theory. The first three chapters can also be adopted for an advanced course in linear algebra. Centered around the concept of projective spectrum, the book presents a coherent treatment of fundamental elements from a
