Boundary value problems for linear differential-algebraic equations: solvability via the Kronecker canonical form
Anar Assanova, Carsten Trunk, Roza Uteshova +1
The solvability of two-point boundary value problems for constant-coefficient differential-algebraic equations is investigated. Unlike previous studies, which often assume that the…
A Jordan-like decomposition for linear relations in finite-dimensional spaces
Thomas Berger, Henk de Snoo, Carsten Trunk +1
A square matrix has the usual Jordan canonical form that describes the structure of via eigenvalues and the corresponding Jordan blocks. If is a linear relation in a fi…
Linear relations and their singular chains
Thomas Berger, Henk de Snoo, Carsten Trunk +1
Singular chain spaces for linear relations in linear spaces play a fundamental role in the decomposition of linear relations in finite-dimensional spaces. In this paper singular ch…
On a class of integral systems
Volodymyr Derkach, Dmytro Strelnikov, Henrik Winkler
We study spectral problems for two--dimensional integral system with two given non-decreasing functions , on an interval which is a generalization of the Krein s…
Finite Rank Perturbations of Linear Relations and Matrix Pencils
Leslie Leben, Francisco Martínez-Pería, Friedrich Philipp +2
We elaborate on the deviation of the Jordan structures of two linear relations that are finite-dimensional perturbations of each other. We compare their number of Jordan chains of…
Global and local behavior of zeros of nonpositive type
Henk de Snoo, Henrik Winkler, Michal Wojtylak
A generalized Nevanlinna function with one negative square has precisely one generalized zero of nonpositive type in the closed extended upper halfplane. The fractional line…
