A Class of Sheffer Sequences of Some Complex Polynomials and Their Degenerate Types

Mathematics, 2019
We study some properties of Sheffer sequences for some special polynomials with complex Changhee and Daehee polynomials introducing their complex versions of the polynomials and splitting them into real and imaginary parts using trigonometric polynomial ...

Threats posed by land use to water quality in South Africa's strategic water source areas

World Water Policy, Volume 11, Issue 1, Page 155-164, February 2025.
Abstract Understanding the negative impacts of land use/land cover (LULC) on water quality is key to developing effective integrated catchment management strategies. However, in line with the Integrated Water Resources Management (IWRM) philosophy, this necessitates the generation and application of useful scientific knowledge, which stakeholders and ...

Scaling up ocean conservation through recognition of key biodiversity areas in the Southern Ocean from multispecies tracking data

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Biodiversity is critical for maintaining ecosystem function but is threatened by increasing anthropogenic pressures. In the Southern Ocean, a highly biologically productive region containing many endemic species, proactive management is urgently needed to mitigate increasing pressures from fishing, climate change, and tourism.

Intertwined precariousness and precarity: Disentangling a phenomenon that characterises Spanish youth

International Journal of Social Welfare, Volume 34, Issue 1, January 2025.
Abstract The growth of non‐standard employment has emerged as a crucial factor that contributes to delays and difficulties in young people's transitions to adulthood. Previous studies have demonstrated the importance of multidimensional measures of precariousness.

On Mittag-Leffler-Gegenbauer polynomials arising by the convolution of Mittag-Leffler function and Hermite polynomials

AIMS Mathematics
Gegenbauer polynomials hold a significant role in the constructive theory of spherical functions, while the Mittag-Leffler function is widely used in fractional calculus.

Identities arising from higher-order Daehee polynomial bases

Open Mathematics, 2015
Here we will derive formulas for expressing any polynomial as linear combinations of two kinds of higherorder Daehee polynomial basis. Then we will apply these formulas to certain polynomials in order to get new and interesting identities involving ...

A new discretization of the Euler equation via the finite operator theory [PDF]

Open Communications in Nonlinear Mathematical Physics
We propose a novel discretization procedure for the classical Euler equation, based on the theory of Galois differential algebras and the finite operator calculus developed by G.C. Rota and collaborators.

Umbral calculus in Ore extensions

Journal of Pure and Applied Algebra, 2020
Abstract The aim of the paper is to show the existence of some ingredients for an umbral calculus on some Ore extensions, in a manner analogous to Rota's classical umbral calculus which deals with a univariate polynomial ring on a field of characteristic zero.

Differential coping capacities underlie the overall resistance of temperate seagrasses to herbivory

Ecosphere, Volume 15, Issue 12, December 2024.
Abstract Grazing can impart long‐lasting changes in vegetated ecosystems. How ecosystems respond to herbivory depends on the ecological and evolutionary histories of their foundational species. The overall ecosystem functioning and associated biodiversity depend on these responses but there is still little understanding on how the intensity and ...
