In this paper we introduce Stein's square function associated with bilinear
Bochner-Riesz means and develop a systematic study of its Lp boundedness
properties. We also discuss applications of bilinear Bochner-Riesz square
function in the context of bilinear fractional Schr\"{o}dinger multipliers,
generalized bilinear spherical maximal function and more general bilinear
multipliers defined on R2n of the form (ξ,η)→m(∣(ξ,η)∣2).Comment: Comments are welcom
