P. Stefanov et G. Vodev, DISTRIBUTION OF RESONANCES FOR THE NEUMANN PROBLEM IN LINEAR ELASTICITY OUTSIDE A BALL, Annales de l'I.H.P. Physique theorique, 60(3), 1994, pp. 303-321
For the Neumann problem in linear elasticity outside a ball in R3 exis
tence of a sequence of resonances converging exponentially fast to the
real axis is proven. It is also shown that there are no other resonan
ces below some cubic parabola.
