报告摘要:The Eigenvalue problem is a fundamental problem in numerical algebra and have many important practical applications. Plenty of numerical methods have been proposed to solve this problem. Taking eigenvalues and all entries of the corresponding eigenvectors as variables, we can transform an eigenvalue problem to a polynomial system. In this talk, I will set a bridge between the eigenpairs of the eigenvalue problem and the complete solution of the polynomial system, and then introduce the numerical methods for polynomial system to solve the eigenvalue problems. Numerical results show that this class of methods is more efficient for large-scale problems.
