An estimate of approximation of a matrix-valued function by an interpolation polynomial

V. G. Kurbatov, I. V. Kurbatova

Let $A$ be a square complex matrix, $z_{1}$ , ..., $z_{n} \in C$ be (possibly repetitive) points of interpolation, $f$ be analytic in a neighborhood of the convex hull of the un…

Inverse-closedness of subalgebras of integral operators with almost periodic kernels

E. Yu. Guseva, V. G. Kurbatov

The integral operator of the form $(N u) (x) = k = 1 \sum \infty e^{i ⟨ ω_{k}, x ⟩} \int_{R^{c}} n_{k} (x - y) u (y) d y$ acting in $L_{p} (R^{c})$ , $1\le p\le\inf…

Green's function of the problem of bounded solutions in the case of a block triangular coefficient

V. G. Kurbatov, I. V. Kurbatova

It is known that the equation $x^{'} (t) = A x (t) + f (t)$ , where $A$ is a bounded linear operator, has a unique bounded solution $x$ for any bounded continuous free term~ $f$ if and only if…
