A Study on the k-Mersenne and k-Mersenne-Lucas Sequences
Universal Journal of Mathematics and ApplicationsIn this study, we examine an application of $k-$Mersenne and $k-$Mersenne-Lucas sequences. We present the Catalan transforms of these sequences and give the properties of these Catalan transforms. Catalan transforms of $k-$Mersenne and $k-$Mersenne-Lucas

Hankel and Toeplitz operators: continuous and discrete representations
, 2016 We find a relation guaranteeing that Hankel operators realized in the space of sequences $\ell^2 ({\Bbb Z}_{+}) $ and in the space of functions $L^2 ({\Bbb R}_{+}) $ are unitarily equivalent.

Nanophotonics, Volume 14, Issue 24, Page 4447-4457, December 2025.Abstract Topologically structured light carrying orbital angular momentum (OAM) has emerged as a powerful tool for nano‐photonics and biomedical optics, yet conventional integer‐charge Laguerre–Gaussian (LG) beams suffer from rotational degeneracy that limits diagnostic precision.

Efficient quantum circuits for Toeplitz and Hankel matrices
, 2016 Toeplitz and Hankel matrices have been a subject of intense interest in a wide range of science and engineering related applications. In this paper, we show that quantum circuits can efficiently implement sparse or Fourier-sparse Toeplitz and Hankel ...

Low‐Energy Atomic Scattering: S‐Wave Relation Between the Interaction Potential and the Phase Shift
Annalen der Physik, Volume 537, Issue 11, November 2025.The validity of the on‐shell approximation for s‐wave scattering is examined across one, two, and three dimensions using exactly solvable model interaction potentials. By comparing exact and approximate s‐wave components of the interaction potential, the analysis reveals that the approximation improves with increasing momentum and decreasing ...

Three methods for performing Hankel transforms [PDF]
Three methods for performing Hankel transforms with optical or digital processors are described. The first method is applicable when the input data is available in Cartesian (x-y) format and uses the close connection between generalized Hankel transform ...

Polynomial computation of Hankel singular values [PDF]
, 1992 A revised and improved version of a polynomial algorithm is presented. It was published by N.J. Young (1990) for the computation of the singular values and vectors of the Hankel operator defined by a linear time-invariant system with a rotational ...
