The $p$-$\delta $-spherical Grassmannian $\mathcal{G}_{p\,\delta }$ is an equivalence class of spherical functions of type $\delta $-positive of height $p$. In this talk\, we construct some elements of $\mathcal{G}_{p\ ,\delta }$ on reductive Lie group using a generalized Abel transform. And if the discret serie is not empty\,we give a extension of Paley Wiener the orem using a compact Cartan subgroup of $G.$\n DTSTART:20190531T173000Z DTEND:20190531T183000Z LOCATION:Room LB 921-4\, CA\, Concordia University SUMMARY:Kinvi Kangni (Universite Felix Houphouet-Boigny) URL:/mathstat/channels/event/kinvi-kangni-universite-f elix-houphouet-boigny-297487 END:VEVENT END:VCALENDAR
