介绍了一种新的振荡函数表示方法
We introduce a new method for functional representation of oscillatory
integrals within any user-supplied accuracy. Our approach is based on
robust methods for nonlinear approximation of functions via exponentials.
The complexity of evaluation of the resulting representations of the
oscillatory integrals does not depend or depends only mildly on the
size of the parameter responsible for the oscillatory behavior.
