In this study, we shall prove that the oscillatory integral operator can be reduced to the study of another contraction oscillatory integral operator, with a fixed point which leads to a sharp estimate.


Key words: Oscillatory integrals operator, bilinear forms, Fourier transform, non singular matrix, intertwining.
