Homogeneous estimates for oscillatory integrals.
Homogeneous even kernels on surfaces.
Hubert integrals, Singular integrals, and Radon transforms II.
Hyperbolic singular integral operators.
We define a class of integral operators which are singular relative to the hyperbolic metric in simply connected domains of the plane. We study the necessary and sufficient conditions for such operators to be bounded on L2 of the upper half plane relative to the hyperbolic metric.
