Resumen de Lp multipliers and their H1-L1 estimates on the Heisenberg group

Ch. Lin

• We give a Hörmander-type sufficient condition on an operator-valued function M that implies the Lp-boundedness result for the operator TM defined by (TMf)^ = Mf^ on the (2n + 1)-dimensional Heisenberg group Hn. Here ^ denotes the Fourier transform on Hn defined in terms of the Fock representations. We also show the H1-L1 boundedness of TM, ||TMf||L1 = C||f||H1, for Hn under the same hypotheses of Lp-boundedness.
