چکیده

In this article generalized attenuated ray transforms (ART) and integral angular moments are investigated. Starting from the Radon transform, transform longitudinal we derive concept of ART-operators order k over functions defined on phase space depending time. The for complex-valued absorption coefficient as well weight polynomial exponential type. Connections between ART operators various orders established by means application linear part a transport equation. These connections lead to inhomogeneous differential equations (k+1) k. Uniqueness theorems corresponding boundary-value initial problems proved. Properties p considered different deduced. A close connection with mathematical models tomography, physical optics geometry allows treat inversion an inverse problem determining right-hand side

On Q-integral Transforms and Their Applications

In this paper, we introduce a q-analogue of the P-Widder transform and give a Parseval-Goldstein type theorem. Furthermore, we evaluate the q-Laplace transform of a product of q-Bessel functions. Several special cases of our results are also pointed out.

Generalized Fourier Transforms and their Applications

This thesis centers around a generalization of the classical discrete Fourier transform. We first present a general diagrammatic approach to the construction of efficient algorithms for computing the Fourier transform of a function on a finite group or semisimple algebra. By extending work which connects Bratteli diagrams to the construction of Fast Fourier Transform algorithms [2], we make exp...

Some Generalized Integral Inequalities and Their Applications

In this paper, we generalize some integral inequalities to more general situations. These on the one hand generalize and on the other hand furnish a handy tool for the study of qualitative as well as quantitative properties of solutions of integral equations and differential equations. Applications are given to illustrate the usefulness of the inequalities.

The Kontorovich – Lebedev Integral Transforms and Their Inverses ∗

The numerical evaluation of the transforms in the title, and their inverses, is considered, using a variety of decomposition, truncation, and quadrature methods. Extensive numerical testing is provided and an application given to the numerical evaluation of the kernel of a Fredholm integral equation of interest in mixed boundary value problems on wedge-shaped domains. AMS subject classification...
