Webthe associated eigenvectors is shown to be more complex in the phononic case. Along a closed loop around an exceptional point, we show that the eigenvectors can ip signs multiple times unlike a 2 by 2 matrix where the ip of sign occurs only once. Finally, we exploit these eigenvector sign WebEssential vocabulary words: eigenvector, eigenvalue. In this section, we define eigenvalues and eigenvectors. These form the most important facet of the structure theory of square matrices. As such, eigenvalues and eigenvectors tend to play a key role in the real-life applications of linear algebra.
