报告摘要：In this talk, we recall the concept of parabolic Muckenhoupt weights with time lag and present related results. By introducing a new parabolic fractional integral operator, we characterize the off-diagonal parabolic Muckenhoupt weights in terms of the weighted boundedness of such operator. Some extrapolation theorems for parabolic Muckenhoupt weights are established, which is then applied to obtain the weighted boundedness for commutators of the aforementioned parabolic fractional integral operator. Finally, we will present recent advances on the optimal real-variable characterizations of parabolic Campanato spaces with time lag.
