Inverse Spectral Problems for a Special Acyclic Matrix

International Journal of Foundations of Computer Science, 2023
In this paper, we consider the reconstruction of matrices whose graph is a star with root at the central vertex from given partial eigen data. Three inverse spectral problems are discussed. The necessary and sufficient conditions for the solvability of the problems are studied. Furthermore, the corresponding numerical algorithms are presented.

Spectral problems for matrix pencils. Methods and algorithms. I

Russian Journal of Numerical Analysis and Mathematical Modelling, 1988
Summary: \([\)For part I, cf. ibid. 3, No. 5, 337-371 (1988)\(]\). \noindent A review of methods and algorithms for solving spectral problems for regular polynomial matrix pencils is presented. Main attention is paid to those methods which are constructed without exploiting the connection between polynomial pencils and linear accompanying pencils or ...

Deflation in spectral problems for matrix pencils

Russian Journal of Numerical Analysis and Mathematical Modelling, 1987
Summary: Algorithms for deflating regular and singular spectral characteristics of \(m \times n\) polynomial matrix pencils of degree \(s \geq 1\) are treated. To deflate regular spectral characteristics, algorithms extending known deflation techniques for matrices are proposed (deflation is applied to general type pencils, new types of spectral ...
