Petrovskii elliptic systems in the extended Sobolev scale
Tetiana Zinchenko, Aleksandr Murach
Petrovskii elliptic systems of linear differential equations given on a closed smooth manifold are investigated on the extended Sobolev scale. This scale consists of all Hilbert sp…

Localization principles for Schrödinger operator with a singular matrix potential
Vladimir Mikhailets, Aleksandr Murach, Viktor Novikov
We study the spectrum of the one-dimensional Schrödinger operator with a matrix singular distributional potential where $Q\in L^{2}_{\mathrm{loc}}(\mathbb{R},\mathbb{C…

Elliptic problems with boundary conditions of high orders in Hörmander spaces
Tetiana Kasirenko, Aleksandr Murach
In a class of inner product Hörmander spaces, we investigate a general elliptic problem for which the maximum of orders of boundary conditions is grater than or equal to the order…
