报告摘要：In this talk, I will be presenting a class of Fourier multipliers and pseudo-differential operators having flag structure in both single and bi-parameter setting. Such flag operators were initially studied by C. Muscalu. Our proof is mainly based on an reduction argument, and it also helps to obtain an associated weighted estimate.
