The connection between different classes of special functions is a very important aspect in establishing new properties of the related classical functions that is they can inherit the properties of each other. Here we show how the Hermite polynomials are

Monotonicity of zeros of Laguerre polynomials
Monotonicity, with respect to a parameter, of certain functions involving the zeros \(x_{nk}(\alpha)\) of the Laguerre polynomial \(L_n^{(\alpha)}(x)\) is studied. It is assumed that the zeros are arranged in decreasing order and it is proved that for any \( n \geq 2\) and \(k=1,\dots,n\), the quantities \[ \frac{x_{nk}(\alpha)-(2n+\alpha-1)}{\sqrt{2(n+

Quantum Dust Cores of Black Holes and Their Quasi‐Normal Modes
We investigate the quasi‐normal mode spectrum of a gravitationally collapsed ball of dust, considering both a linear and a refined parabolic effective mass function for the quantum core. Furthermore, we account for the quantum leakage of dust particles outside the horizon.

Extended Laguerre Polynomials Associated with Hermite, Bernoulli, and Euler Numbers and Polynomials
Let Pn={p(x)∈ℝ[x]∣deg p(x)≤n} be an inner product space with the inner product 〈p(x),q(x)〉=∫0∞xαe-xp(x)q(x)dx, where p(x),q(x)∈Pn and α∈ℝ with α>-1. In this paper we study the properties of the extended Laguerre polynomials which are an orthogonal basis

On moments of the derivative of CUE characteristic polynomials and the Riemann zeta function
Abstract We study the derivative of the characteristic polynomial of N×N$N \times N$ Haar‐distributed unitary matrices. We obtain new explicit formulae for complex‐valued moments when the spectral variable is inside the unit disc, in the limit N→∞$N \rightarrow \infty$.

Asymptotic zero distribution of Jacobi-Pi\~neiro and multiple Laguerre polynomials
We give the asymptotic distribution of the zeros of Jacobi-Pi\~neiro polynomials and multiple Laguerre polynomials of the first kind. We use the nearest neighbor recurrence relations for these polynomials and a recent result on the ratio asymptotics of ...

A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...
