Chung, Eric T.; Zou, Jun The eigenvalues and eigenspaces of some discrete div- and curl-related operators. (English) Zbl 1038.65118 SIAM J. Matrix Anal. Appl. 24, No. 4, 1149-1160 (2003). The paper deals with the eigenvalues and eigenspaces of some discrete div- and curl-related operators. The discrete operators give some good analogues of the continuous counterparts and play an importent role in developing finite volume schemes for solving div-curl equations and electromagnetics systems. Knowledge of the eigenvalues and eigenspaces is very useful in the numerical analysis of finite volume methods for electromagnetic systems in nonhomegeneous media.
