报告摘要: First we comment about multilinear weights introduced by Lerner, Ombrossi, Perez, et al, and by Yulan Jiao. We give several nonintegrable weights consisting multilinear weights. To show weighted boundedness for multilinear Fourier multiplier operators, the usual way is first to establish the boundedness for truncated good operators, then, using the density argument to get the transition from good operators to the Fourier multiplier operators. However, this step is not clear for nonintegrable weight. In this talk, I will present a way avoiding to use the density argument.
