摘要
Let Delta be full Laplacian on H -type group G. Then for every compact set D subset of G, a local estimate of the Schr5dinger maximal operator holds, that is, integral(D0<t<1)sup|e(it Delta)f(x)|(2)dx less than or similar to||f||H-2(s) s>1/2. We also show that the above inequality fails when s < 1/4.
