摘要
The purpose of this paper is to present a method of characterising polyhomogeneous Lagrangian distributions via testing by pseudo-differential operators. The concept of a radial operator fur a Lagrangian submanifold is introduced, and polyhomogeneous Lagrangian distributions are shown to be the only Lagrangian distributions which are eigenfunctions at the top order for these operators.
