Yet Another Face of the Creation Operator,le the operator of multiplication by the independent variable in the Segal-Bargmann space does as another. In a finite difference operator . was recorded. It may be considered as yet another face of the creation one. Our intension here is to invite attention to this operator by considering the

Complementary Triangular Forms for Infinite Matrices,angular, and ... is lower triangular. This paper presents analogues of this result for pairs of bounded operators, acting on the separable Hilbert space ..(..). The main result states that there exist two diagonable operators . and . acting on ..(..), that are not simultaneously similar respectivily

Analysis of the Radiation Loss: Asymptotics Beyond all Orders, The other boundary condition is imposed at ϰ = +∞. Several authors have computed a desired quantity Im.(0;λ), which is called the radiation loss, for several special cases. The radiation loss problem is an nonlinear eigenvalue problem. In this paper, we try to have a general discussion for a variety of functions ..

Rayleigh Problem and Friedrichs Model, technique is applied to obtain corresponding eigen-function expansion theorem in the case when velocity profile of main stationary flow is close to linear. Besides, inverse scattering problem related to Rayleigh equation is considered. Local solvability of this problem and local uniqueness property are established.

On Transformation of Canonical Systems, a function of .. The function . is called the . of the canonical system (0.1). if ., it has a unique .. where σ is a nonnegative measure which is called the . of the canonical system given by (0.1). We call the canonical system . if its spectral measure σ is a finite sum of point measures.
