BOUNDARY VALUE PROBLEMS FOR INTEGRAL EQUATIONS WITH OPERATOR MEASURES
Journal Title: Проблемы анализа-Issues of Analysis - Year 2017, Vol 6, Issue 1
Abstract
We consider integral equations with operator measures on a segment in the infinite-dimensional case. These measures are defined on Borel sets of the segment and take values in the set of linear bounded operators acting in a separable Hilbert space. We prove that these equations have unique solutions and we construct a family of evolution operators. We apply the obtained results to the study of linear relations generated by an integral equation and boundary conditions. In terms of boundary values, we obtain necessary and sufficient conditions under which these relations T possess the properties: T is a closed relation; T is an invertible relation; the kernel of T is finite-dimensional; the range of T is closed; T is a continuously invertible relation and others. We give examples to illustrate the obtained results.

УСЛОВНЫЕ И ВЗАИМНЫЕ МУЛЬТИФРАКТАЛЬНЫЕ СПЕКТРЫ. ОПРЕДЕЛЕНИЕ И ОСНОВНЫЕ СВОЙСТВА
This paper introduces a formalism for the multifractal analysis of one probability measure with respect to another. The conditional and the mutual multifractal spectra are considered, which give the better understanding...
Solvability of the difference equations for the dynamics of cumulative sums
We consider the linear system of difference equations for the cumulative sum used in detecting network attacks. In the flow of events each can be dangerous with the known probability, in this case the cumulative sum is i...
Cauchy projectors on non-smooth and non-rectifiable curves
Let f (t) be defined on a closed Jordan curve Γ that divides the complex plane on two domains D + , D − , ∞ ∈ D − . Assume that it is representable as a difference f (t) = F + (t) − F − (t), t ∈ Γ, where F ± (t) are limi...
ON WEIGHTED GENERALIZED FUNCTIONS ASSOCIATED WITH QUADRATIC FORMS
In this article we consider certain types of weighted generalized functions associated with nondegenerate quadratic forms. Such functions and their derivatives are used for constructing fundamental solutions of iterated...
EXTENSION OF STARLIKE FUNCTIONS TO A FINITELY PUNCTURED PLANE
We consider a sequence of functions which are starlike in the unit disk and their logarithmic derivatives are meromorphic with a finite number of simple poles in any boundary domain. These poles are either boundary deter...
