On Limits of Sequences of Resolvent Kernels for Subkernels

Igor M. Novitskii

In this paper, we approximate to continuous bi-Carleman kernels vanishing at infinity by sequences of their subkernels of Hilbert-Schmidt type and try to construct the resolvent ke…

Some properties of the resolvent kernels for continuous bi-Carleman kernels

Igor M. Novitskii

We prove that, at regular values lying in a strong convergence region, the resolvent kernels for a continuous bi-Carleman kernel vanishing at infinity can be expressed as uniform l…

On Fredholm's Integral Equations on the Real Line, Whose Kernels Are Linear in a Parameter

Igor M. Novitskii

In this paper, we study an infinite system of Fredholm series of polynomials in , formed, in the classical way, for a continuous Hilbert-Schmidt kernel on $\mathbb{R}\times\math…

Kernels of Integral Equations Can Be Boundedly Infinitely Differentiable on

Igor M. Novitskii

In this paper, we reduce the general linear integral equation of the third kind in , with largely arbitrary kernel and coefficient, to an equivalent integral equation eit…

Integral operators with infinitely smooth bi-Carleman kernels of Mercer type

Igor M. Novitskii

With the aim of applications to solving general integral equations, we introduce and study in this paper a special class of bi-Carleman kernels on , cal…

Simultaneous unitary equivalence to Carleman operators with arbitrarily smooth kernels

Igor M. Novitskii

In this paper, we describe families of those bounded linear operators on a separable Hilbert space that are simultaneously unitarily equivalent to integral operators on wi…
