报告摘要：

Matrix joint block diagonalization problem is a particular block term

decomposition of third order tensors, which has many

important applications in blind source separation and independent

component analysis. In this talk, I will talk about two classes

of algebraic methods for JBD problem: one is based on matrix

polynomial, the other is based on matrix commutation.

Existence and uniqueness conditions for JBD problem are discussed.

Numerical methods are developed and validated by simulating examples.
