Conferenza di ANALISI ARMONICA Giovedì 1 giugno 2006 ore 15.00 Scuola Normale Superiore Pisa (Aula Mancini) Elias M. Stein Princeton University Terrà una conferenza dal titolo: "Some discrete analogues in harmonic analysis" Abstract We will review and survey the background and some recent results concerning discrete analogues that arise in harmonic analysis. When the corresponding R^n results involve "curvature", the passage to their discrete analogues requires estimates for exponential sums of the kind that are used in the circle method. In the classical setting these exponential sums are scalar-valued, but here one needs operator-valued analogues. This will be illustrated in the situation of the Heisenberg group, where the curvature is inherent in its underlying symplectic form. Tutti gli interessati sono invitati a partecipare. _______________________________________________ Settimanale mailing list Settimanale@mail.dm.unipi.it https://mail.dm.unipi.it/mailman/listinfo/settimanale
