Invariant subspaces of $H^{2} (T^{2})$ and $L^{2} (T^{2})$ preserving compatibility

Zbigniew Burdak, Marek Kosiek, Patryk Pagacz +1

Operators of multiplication by independent variables on the space of square summable functions over the torus and its Hardy subspace are considered. Invariant subspaces where the o…

Random Perturbations of Matrix Polynomials

Patryk Pagacz, Michał Wojtylak

A sum of a large-dimensional random matrix polynomial and a fixed low-rank matrix polynomial is considered. The main assumption is that the resolvent of the random polynomial conve…
