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…

Spectrum of -frame operators
Juan Ignacio Giribet, Matthias Langer, Leslie Leben +3
A -frame is a frame for a Krein space which is compatible with the indefinite inner product in the sense that it induces an…

The effect of finite rank perturbations on Jordan chains of linear operators
Jussi Behrndt, Leslie Leben, Francisco Martínez Pería +1
A general result on the structure and dimension of the root subspaces of a matrix or a linear operator under finite rank perturbations is proved: The increase of dimension from the…
