Asymptotic expansions for some integrals of quotients with degenerated divisors
Résumé
We study asymptotic expansion as ν → 0 for integrals over R 2d = {(x, y)} of quotients F (x, y) (x · y) 2 + (νΓ(x, y)) 2 , where Γ is strictly positive and F decays at infinity sufficiently fast. Integrals of this kind appear in description of the four-waves interactions.
