Recurrence relations for higher moments of order statistics from doubly truncated Burr distribution
Statistica, 2014 In this paper, we have obtained recurrence relations for higher moments of order statistics from doubly truncated Burr distribution, which enable one to obtain all the single, double (product) and higher moments of any order of all order statistics for ...

Recurrence relations satisfied by some arithmetic groups
Open MathematicsRecently, recurrence relations satisfied by the modular traces of the Hauptmodul for Γ0(N){\Gamma }_{0}\left(N) of genus zero have been established. However, these relations do not determine all values of the modular traces.

On the Two-Variable Analogue Matrix of Bessel Polynomials and Their Properties
AxiomsIn this paper, we explore a study focused on a two-variable extension of matrix Bessel polynomials. We initiate the discussion by introducing the matrix Bessel polynomials involving two variables and derive specific differential formulas and recurrence ...

Journal of Statistical Theory and Applications (JSTA), 2019 In this paper we obtain exact expressions and some recurrence relations satisfied by single and product moments of dual generalized order statistics from exponentiated Rayleigh distribution. These relations are deduced for moments of order statistics and

A converse of Sturm's separation theorem
Electronic Journal of Qualitative Theory of Differential Equations, 2021 We show that Sturm's classical separation theorem on the interlacing of the zeros of linearly independent solutions of real second order two-term ordinary differential equations necessarily fails in the presence of a turning point in the principal part ...

Identities in the spirit of Euler
Extracta Mathematicae, 2020 In this paper we develop new identities in the spirit of Euler. We shall investigate and report on new Euler identities of weight p + 2, for p an odd integer, but with a non unitary argument of the harmonic numbers.

D-Finite Discrete Generating Series and Their Sections
MathematicsThis paper investigates D-finite discrete generating series and their sections. The concept of D-finiteness is extended to multidimensional discrete generating series and its equivalence to p-recursive sequences is rigorously established.

MathematicsThis paper presents a novel generalization of the mth-order Laguerre and Laguerre-based Appell polynomials and examines their fundamental properties. By establishing quasi-monomiality, we derive key results, including recurrence relations, multiplicative

Revisiting some r-Fibonacci sequences and Hessenberg matrices [PDF]
Notes on Number Theory and Discrete MathematicsThe relationship between different generalizations of Fibonacci numbers and matrices is common in the literature. However, the basic relation of such sequences with Hessenberg matrices is often not properly explored.
