On the basis of a generalization of the well-known Schmidt lemma to the case of linear,
bounded, normally solvable operators in Banach spaces, we propose a procedure for the …

On the basis of generalization of the well-known Schmidt lemma to the case of linear
bounded normally solvable operators in Banach spaces, we propose a procedure for the …

Let X and Y be infinite-dimensional Banach spaces. We will denote the set of the continuous
linear operators that act from X into Y by L (X, Y) and the set of injective operators by L0 (X …

Linear differential operators (equations) of the second order in Banach spaces of vector
functions defined on the entire real axis are studied. Conditions of their invertibility are given …

We find a formula for a unique pseudoinverse operator to a normally solvable equation in a
Hilbert space, as well as existence conditions and a representation of a single solution of the …

Исследуется класс уравнений в банаховых пространствах с интегро-
дифференциальным оператором типа Римана—Лиувилля с операторнозначным …

One of the directions of generalization of the Hahn-Banach theorem on the extension of a
linear functional majorized by a sublinear functional is the study of sublinear operators …

We propose new methods for the construction of generalized inverse operator matrices for
the operator matrices in Banach spaces. The solvability criteria and the formulas for …
