Laplacian operators and Radon transforms on Grassmann graphs

J. M. Marco, J. Parcet

Let $Ω$ be a vector space over a finite field with q elements. Let G denote the general linear group of endomorphisms of $Ω$ and let us consider the left regular representation $ρ:…

A new approach to the theory of classical hypergeometric polynomials

José Manuel Marco, Javier Parcet

In this paper we present a unified approach to the spectral analysis of an hypergeometric type operator whose eigenfunctions include the classical orthogonal polynomials. We write…

On the natural representation of $S (Ω)$ into $L^{2} (P (Ω))$ : Discrete harmonics and Fourier transform

José Manuel Marco, Javier Parcet

Let $Ω$ denote a non-empty finite set. Let $S (Ω)$ stand for the symmetric group on $Ω$ and let us write $P (Ω)$ for the power set of $Ω$ . Let $ρ : S (Ω) \to U (L^{2} (P (Ω)))$ be the left…
