报告摘要：This presentation elucidates computational methodologies for determining the C-eigenvalues and associated C-eigenvectors, as well as the time-varying eigenpairs (specifically the H- and Z-eigenpairs), of a time-invariant piezoelectric-type tensor and time-varying symmetric tensors, respectively. The computation of C-eigenvalues involves employing a conversion technique to transform it into a Z-eigenpair solving problem. Additionally, for addressing the challenge of time-varying tensor eigenpairs, a dynamic method is proposed. Theoretical analysis confirms the feasibility of these methods, and the proposed algorithm's effectiveness is substantiated through examination of multiple numerical examples.
