Abstract: Combining TT argument and bilinear interpolation, this paper obtains the Strichartz and smoothing estimates of dispersive semi-group eitP(D) in weighted L2 spaces. Among other things, we recover the results in [1]. Moreover, the application of these results to the well-posedness of some equations are shown in the last section.

Key words: Strichartz estimates, smoothing estimates, Morrey-Campanato class, weighted L2 spaces, well-posedness
