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…

Sharp Fourier type and cotype with respect to compact semisimple Lie groups

José García-Cuerva, José Manuel Marco, Javier Parcet

Sharp Fourier type and cotype of Lebesgue spaces and Schatten classes with respect to an arbitrary compact semisimple Lie group are investigated. In the process, a local variant of…
