BILINEAR FOURIER INTEGRAL OPERATORS
"... Abstract. We study the boundedness of bilinear Fourier integral operators on products of Lebesgue spaces. These operators are obtained from the class of bilinear pseudodifferential operators of Coifman and Meyer via the introduction of an oscillatory factor containing a realvalued phase of five var ..."

Bilinear operators with nonsmooth symbol
 I, J. Fourier Anal. Appl
"... � � � This paper proves the L pboundedness of general bilinear operators associated to a symbol or multiplier which need not be smooth. The Main Theorem establishes a general result for multipliers that are allowed to have singularities along the edges of a cone as well as possibly at its vertex. ..."

The Marcinkiewicz multiplier condition for bilinear operators
 Studia Math. 146 (2001), 115–156. LOUKAS GRAFAKOS
"... Abstract. This article is concerned with the question of whether Marcinkiewicz multipliers on R2n give rise to bilinear multipliers on Rn × Rn.We show that this is not always the case. Moreover we find necessary and sufficient conditions for such bilinear multipliers to be bounded. These conditions ..."

in particular imply that a slight logarithmic modification of the Marcinkiewicz condition gives multipliers for which the corresponding bilinear operators are bounded on products of Lebesgue and Hardy spaces. 1.
COMPACT BILINEAR OPERATORS AND COMMUTATORS

"... Abstract. A notion of compactness in the bilinear setting is explored. Moreover, commutators of bilinear CalderónZygmund operators and multiplication by functions in a certain subspace of the space of functions of bounded mean oscillations are shown to be compact. 1. ..."

INVARIANT BILINEAR DIFFERENTIAL OPERATORS
, 2005
"... Abstract. Let M be an ndimensional manifold, V the space of a representation ρ: GL(n) − → GL(V). Locally, let T(V) be the space of sections of the tensor bundle with fiber V over a sufficiently small open set U ⊂ M, in other words, T(V) is the space of tensor fields of type V on U. In T(V), the gro ..."

(V), the group Diff(U) of diffeomorphisms of U naturally acts by means of ρ applied to the Jacobi matrix of the diffeomorphism at the point. Here I give the details of the classification of the Diff(M)invariant differential operators D: T(V1) ⊗ T(V2) − → T(V3) for irreducible fibers with lowest weight. Up
BILINEAR OPERATORS ON HOMOGENEOUS GROUPS
"... Let H p denote the Lebesgue space L p for p>1 and the Hardy space H p for p ≤ 1. For 0 <p,q,r<∞, we study H p × H q → H r mapping properties of bilinear operators given by finite sums of products of Calderón–Zygmund operators on stratified homogeneous Lie groups. When r ≤ 1, we show that su ..."
