Dong, Dong et Li, Xiao Chun, On a hybrid of bilinear Hilbert transform and paraproduct, Acta mathematica Sinica. English series (Print) , 34(1), 2018, pp. 29-41
We introduce a class of tri-linear operators that combine features of the bilinear Hilbert transform and paraproduct. For two instances of these operators, we prove boundedness property in a large range D=...(p1,p2,p3).R3:1<p1,p2<.,1p1+1p2<32,1<p3<.....
