In this paper, we introduce a new set of functions, which have the property of the completeness over a finite and infinite intervals. This family of functions, denoted for simplicity GOSWFs, are a generalization of the oblate spheroidal wave function

The goal of this chapter is to solve a concentration of energy problem associated with the Special Affine Fourier Transformation (SAFT). Since an explicit, closed form solution seems to be elusive, we will solve the problem numerically. The problem c

In this work, we study the existence of solutions of the deconvolution problems in the discrete setting. More precisely, we prove the existence of solutions of the discrete multichannel deconvolution problems DMDP with convolvers being the characteri

In this paper, we build a stable scheme for the solution of a deconvolution problem of the Abel integral equation type. This scheme is obtained by further developing the orthogonal polynomial-based techniques for solving the Abel integral equation of

In this paper, we describe two stable methods for the inversion of the Abel integral operator of the first kind. The first method is based on the use of appropriate families of orthonormal polynomials of Jacobi type that constitute orthonormal bases
