Approximation results on Dunkl generalization of Phillips operators via q-calculus
Advances in Difference Equations, 2019 The main purpose of this paper is to construct q-Phillips operators generated by Dunkl generalization. We prove several results of Korovkin type and estimate the order of convergence in terms of several moduli of continuity.

Hankel transform, K-Bessel functions and zeta distributions in the Dunkl setting [PDF]
, 2023 We study analytic aspects of the Dunkl-type Hankel transform, which goes back to Baker and Forrester and, in an earlier symmetrized version, to Macdonald.

Characterization of q-Dunkl Appell symmetric orthogonal q-polynomials [PDF]
, 2010 We introduce a q-Dunkl operator T(θ,q)≔Hq+θH−1 where Hq is the q-derivative one and we determine all symmetric T(θ,q)-Appell classical orthogonal q-polynomials.

Changing Gender Relations in Canada: The Rise of Gender‐Neutral Forenames
Canadian Review of Sociology/Revue canadienne de sociologie, Volume 63, Issue 2, May 2026.ABSTRACT Historically, gender‐neutral or androgynous first names have been relatively rare, showing little sign of upward or downward temporal trend in Canada or elsewhere. Using digitized birth registration records from three provinces (Alberta, British Columbia, and Ontario) and for all of Canada, we highlight a rise, beginning around 1990, in the ...

q-Analogue of the Dunkl Transform on the Real Line [PDF]
, 2016 [[abstract]]In this paper, we consider a q-analogue of the Dunkl operator on R, we dene and study its associated Fourier transform which is a q- analogue of the Dunkl transform.

Dirac Operators for the Dunkl Angular Momentum Algebra [PDF]
, 2022 We define a family of Dirac operators for the Dunkl angular momentum algebra depending on certain central elements of the group algebra of the Pin cover of the Weyl group inherent to the rational Cherednik algebra.

A Miyaoka–Yau inequality for hyperplane arrangements in CPn$\mathbb {CP}^n$
Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.Abstract Let H$\mathcal {H}$ be a hyperplane arrangement in CPn$\mathbb {CP}^n$. We define a quadratic form Q$Q$ on RH$\mathbb {R}^{\mathcal {H}}$ that is entirely determined by the intersection poset of H$\mathcal {H}$. Using the Bogomolov–Gieseker inequality for parabolic bundles, we show that if a∈RH$\mathbf {a}\in \mathbb {R}^{\mathcal {H}}$ is ...

Sedimentology, Volume 73, Issue 2, Page 418-440, February 2026.ABSTRACT The early Cambrian transgression that flooded continental margins worldwide produced extensive sedimentary records that archive valuable information about palaeogeography and basin dynamics. This study integrates detrital zircon U–Pb geochronology and wholerock geochemistry from the Myeonsan and Myobong formations of the basal Taebaek Group ...

Dunkl positive denite functions [PDF]
, 2017 [[abstract]]We introduce the notion of Dunkl positive definite and strictly positive definite functions on R^d. This done by the use of the properties of Dunkl translation. We establish the analogue of Bochner's theorem in Dunkl setting.

Approximation and Orthogonality on Fully Symmetric Domains
Studies in Applied Mathematics, Volume 156, Issue 1, January 2026.ABSTRACT We study orthogonal polynomials on a fully symmetric planar domain Ω$\Omega$ that is generated by a certain triangle in the first quadrant. For a family of weight functions on Ω$\Omega$, we show that orthogonal polynomials that are even in the second variable on Ω$\Omega$ can be identified with orthogonal polynomials on the unit disk composed ...
