NON-LINEAR MULTIPARAMETER EIGENVALUE PROBLEMS
Quaestiones Mathematicae, 1981ABSTRACT In some recent papers [1, 3, 4] we discussed non-linear multiparameter systems of second order ordinary differential equations and paid particular attention to the phenomenon of bifurcation from eigenvalues. Here we present results to cover the abstract case in which our problems are posed in the language of operator theory.

Computations of Holomorphic Multiparameter Eigenvalue Problems
SIAM Journal on Numerical Analysis, 1984The paper concerns multiparameter eigenvalue problems (1) \(A(\lambda,\nu,\mu)u=0\), \(\lambda\),\(\nu\in C\), \(\mu \in C^ m\), \(m\in N\), when A(\(\lambda\),\(\nu\),\(\mu)\) is a linear Fredholm operator with index 0 between Banach spaces E, F which is bounded, holomorphic on a region \(g\subset C^{m+2}\). The isolated eigenvalues \(\lambda =\lambda

Numerical Solution of Multiparameter Eigenvalue Problems
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1982AbstractIn this paper we describe an algorithm for the computation of eigenvalue curves and corresponding eigenvectors of multiparameter eigenvalue problems. After input of an algebraic simple eigenvalue with eigenvector we use continuation methods to compute the eigenvalue curve starting from the given eigenvalue.

Multiparameter Variational Eigenvalue Problems With Indefinite Nonlinearity
Canadian Journal of Mathematics, 1997AbstractWe consider the multiparameter nonlinear Sturm-Liouville problemwhere are parameters. We assume that1 ≤ q ≤ p1 < p2 < ... ≤ pn < 2q + 3.We shall establish an asymptotic formula of variational eigenvalue λ = λ(μ, α) obtained by using Ljusternik-Schnirelman theory on general level set Nμ, α(α < 0 : parameter of level set ...

A Variational Approach to Multiparameter Eigenvalue Problems for Matrices
SIAM Journal on Mathematical Analysis, 1977The variational theory of eigenvalues and eigenvectors is extended to the multiparameter problem $(T_r + \sum_{s = 1}^k {\lambda _s V_{rs} } )x_r = 0$, $r = 1, \cdots ,k$ where $T_r $ and $V_{rs} $...
