Weighted and endpoint estimates for commutators of bilinear pseudo-differential operators

In this paper, by applying the accurate estimates of the Hormander class, the authors consider the commutators of bilinear pseudo-differential operators and the operation of multiplication by a Lipschitz function. By establishing the pointwise estimates of the corresponding sharp maximal function, the boundedness of the commutators is obtained respectively on the products of weighted Lebesgue spaces and variable exponent Lebesgue spaces with sigma is an element of B BS1,1.1 Moreover, the endpoint estimate of the commutators is also established on L-infinity x L-infinity.
