寻求复矩阵、四元数矩阵及其实矩阵关联的进阶书籍推荐

Hey there! Since you're already working through Matrix groups for undergraduates by K. Tapp, here are some top-tier advanced texts that dig deep into complex matrices, quaternionic matrices, and their critical connections to real matrices—perfect for taking your understanding to the next level:

• 《Matrix Analysis》by Roger A. Horn and Charles R. Johnson
  This is the undisputed gold standard for advanced matrix theory. It dedicates extensive, rigorous sections to complex matrix properties (including unitary matrices, Schur decomposition, and spectral theory for complex operators) while drawing clear, explicit parallels to real matrix behavior. Later chapters also cover quaternionic matrices, framing them as natural extensions of real/complex structures—great for building a unified, interconnected understanding of all three matrix types.

• 《Quaternionic Matrices: Theory and Applications》by Fuzhen Zhang
  If you want a focused, deep dive specifically into quaternionic matrices, this book is essential. It systematically links quaternionic matrix theory to real and complex matrix analogs, covering everything from eigenvalue problems and matrix decompositions to applications in physics, signal processing, and engineering. It’s ideal for bridging the gap between the real/complex matrix knowledge you’re building and the more non-commutative quaternionic framework.

• 《Advanced Linear Algebra》by Steven Roman
  Taking a more algebraically foundational approach, this text explores the structural relationships between real, complex, and quaternionic vector spaces and their associated matrices. It covers topics like tensor products, Clifford algebras, and the embedding of real matrices into complex or quaternionic matrix algebras—perfect if you want to understand the core structural connections between these matrix types, not just their surface-level properties.

• 《Complex Matrices and Applications》by Ian R. Porteous
  This book centers on complex matrix theory but consistently contextualizes it against real matrix counterparts. It includes detailed sections on how real matrices can be represented via complexification, and touches on quaternionic matrices as a further generalization. The inclusion of applications to geometry, quantum mechanics, and differential equations adds practical depth to the theoretical links between real, complex, and quaternionic matrices.

All of these texts build seamlessly on the undergraduate-level matrix group theory you’re studying, so you’ll find familiar concepts expanded into more advanced, unified frameworks. Happy reading!
