An optimal criterion for $L^2\times L^2 \to L^1$ boundedness.

Abstract:

In the absence of Plancherel's identity on $L^1$, we obtain a nearly sharp condition for bilinear multiplier operators to be bounded from $L^2\times L^2 \to L^1$. We discuss several applications. This is a joint work with L. Grafakos and D. He.
