A functional model for a commutative system of the linear bounded operators {T₁, T₂}, when T₁ is a contraction, is built. 2008-01-01T00:00:00Z Orthogonal Polynomials on Rays: Properties of Zeros, Related Moment Problems and Symmetries Zagorodnyuk, S.M. http://dspace.nbuv.gov.ua:80/handle/123456789/106515 2016-09-30T00:02:58Z 2008-01-01T00:00:00Z Orthogonal Polynomials on Rays: Properties of Zeros, Related Moment Problems and Symmetries Zagorodnyuk, S.M. We establish some basic properties of zeros for orthonormal polynomials on radial rays. We introduce a moment problem related to these orthonormal polynomials and obtain necessary and sufficient conditions for its solvability. We establish some properties of orthonormal polynomials in the case when the measure of orthogonality has symmetries and show that the moment problem has solutions with some symmetric properties. 2008-01-01T00:00:00Z On Subharmonic Functions of the First Order with Restrictions on the Real Axis Poedintseva, I.V. http://dspace.nbuv.gov.ua:80/handle/123456789/106514 2016-09-30T00:03:02Z 2008-01-01T00:00:00Z On Subharmonic Functions of the First Order with Restrictions on the Real Axis Poedintseva, I.V. 2008-01-01T00:00:00Z
