摘要
The problem of finding the differentiability conditions for bilinear Fourier multipliers that are as small as possible to ensure the boundedness of the corresponding operators from products of Hardy spaces H-P1 X H-P2 to L-P, 1/p(1) + 1/p(2) = 1/p, is considered. The minimal conditions in terms of the product type Sobolev norms are given for the whole range 0 < p(1),p(2) <= infinity.
