In this paper, we study a class of Lagrangian submanifolds which may be viewed as intersecting at infinity. They are objects naturally associated with a class of tempered oscillatory integrals. In this context, we prove the adapted versions of the classical theorems, such as parametrization results, as well as equivalence of phase functions.

Abstract
In this paper, we study a class of Lagrangian submanifolds which may be viewed as intersecting at infinity. They are objects naturally associated with a class of tempered oscillatory integrals. In this context, we prove the adapted versions of the classical theorems, such as parametrization results, as well as equivalence of phase functions.
