Bilinear multipliers on Lorenzt spaces
Francisco Villarroya
We give one sufficient and two necessary conditions for boundedness between Lebesgue or Lorentz spaces of several classes of bilinear multiplier operators closely connected with th…

Transference of bilinear multiplier operators on Lorentz spaces
Oscar Blasco, Francisco Villarroya
We prove a DeLeeuw type theorem of transference of boundedness for modulation invariant multiplier operators between the groups defined by the real line and the torus.
