Abstract
In [0,Π] we consider the complete orthogonal system Pn associated to the weight function ψ = r(2r - l)n-1 sin2 Ø(r2 - (2r - l)cos2 Øxs)-1 and we study mean and pointwise convergence of series expansions with respect to the system Pn in Lp([0, 7r], ch/>). This weight function, and the corresponding system Pn arise from the study of Gelfand transforms of radial functions on a finitely generated free group Fr and our results can be interpreted in terms of multipliers theory on FrI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
