Weighted Finite Laplace Transform Operator: Spectral Analysis and Quality of Approximation by its Eigenfunctions

NourElHouda Bourguiba, Abderrazek Karoui

For two real numbers $c > 0, α > - 1,$ we study some spectral properties of the weighted finite bilateral Laplace transform operator, defined over the space $E = L^{2} (I, ω_{α}),$ $I = [- 1, 1],$ …

Non-Asymptotic behaviour of the spectrum of the Sinc Kernel Operator and Related Applications

Aline Bonami, Philippe Jaming, Abderrazek Karoui

Prolate spheroidal wave functions have recently attracted a lot of attention in applied harmonic analysis, signal processing and mathematical physics. They are eigenvectors of the…
