Abstract
Oscillatory integral of the form ε e i(x·u+tP(x)) ∝(x)dx is discussed in this paper; type of critical point of a polynomial is introduced; asymptotic behaviour of the oscillatory integral is given; finally, a restriction theorem of Fourier Transform on algebraic hypersurface (x1, x2, ..., x n , P(x)) is obtained as an application.
