Sharp estimates for oscillatory integral operators via polynomial partitioning
The sharp range of L -estimates for the class of Hörmander-type oscillatory integral operators is established in all dimensions under a positive-definite assumption on the phase. This is achieved by generalising a recent approach of the first author for studying the Fourier extension operator, which...
