Numerical methods for rectangular multiparameter eigenvalue problems, with applications to finding optimal ARMA and LTI models [PDF]
Standard multiparameter eigenvalue problems (MEPs) are systems of k≥2$$ k\ge 2 $$ linear k$$ k $$ ‐parameter square matrix pencils. Recently, a new form of multiparameter eigenvalue problems has emerged: a rectangular MEP (RMEP) with only one ...

Fiber product homotopy method for multiparameter eigenvalue problems [PDF]
We develop a new homotopy method for solving multiparameter eigenvalue problems (MEPs) called the fiber product homotopy method. For a k-parameter eigenvalue problem with matrices of sizes n1,…,nk=O(n)\documentclass[12pt]{minimal} \usepackage{amsmath ...

Comparison cones for multiparameter eigenvalue problems
AbstractWe consider the multiparameter eigenvalue problem (Tr + ∑s = 1k λs Vrs) xr = 0, xr ≠ 0, 1 ⩽ r ⩽ k, where Tr and Vrs are self-adjoint linear operators on Hilbert spaces Hr, the Vrs being bounded. The problem may be posed in either ⊕r = 1k Hr or ⊕r = 1k Hr and we develop variational approaches for both settings.

A Newton method for solving locally definite multiparameter eigenvalue problems by multiindex
We present a new approach to compute eigenvalues and eigenvectors of locally definite multiparameter eigenvalue problems by its signed multiindex. The method has the interpretation of a semismooth Newton method applied to certain functions that have a ...

Discretization of multiparameter eigenvalue problems
Although multiparameter eigenvalue problems, as for example Mathieu's differential equation, have been known for a long time, so far no work has been done on the numerical treatment of these problems. So in this paper we extend the spectral theory for one parameter (cf.

Abstract oscillation theorems for multiparameter eigenvalue problems
AbstractWe prove abstract analogous of Klein's oscillation theorem by demonstrating the existence (and in some cases uniqueness) of eigenpairs with a given index for the multiparameter problem Tmxm = ∑n = 1k λnVmnxm, 0 ≠ xm ϵ Hm, m = 1 … k. (∗) Here Tm and Vmn are self-adjoint operators on Hilbert spaces Hm. The index is based on the number of negative

Two Double Recursive Block Macaulay Matrix Algorithms to Solve Multiparameter Eigenvalue Problems
We present two double recursive block Macaulay matrix algorithms to solve multiparameter eigenvalue problems (MEPs). In earlier work, we have developed a non-recursive approach that finds the solutions of an MEP via a multidimensional realization problem

Subspace method for multiparameter‐eigenvalue problems based on tensor‐train representations [PDF]
In this article, we solve m ‐parameter eigenvalue problems ( m EPs), with m any natural number by representing the problem using tensor‐trains (TTs) and designing a method based on this format.

Roots of bivariate polynomial systems via determinantal representations [PDF]
We give two determinantal representations for a bivariate polynomial. They may be used to compute the zeros of a system of two of these polynomials via the eigenvalues of a two-parameter eigenvalue problem.
