报告摘要： In this talk,  I will speak of the metric theory of a limsup set of rectangles where the sidelengths of the rectangles are far beyond being comparable. More precisely, the metric theory of the following limsup set coming from a combination of Diophantine approximation and shrinking

target problem {(x,y): \|qx\|<\psi_1(q), \|2^qy\|<\psi_2(q), i.m. q\in \N}.
