Recovering Asymptotics at Infinity of Perturbations of Stratified Media
We consider perturbations of a stratified medium ℝ x n-1 ×ℝ y , where the operator studied is c 2 (x,y)Δ. The function c is a perturbation of c 0 (y), which is constant for sufficiently large |y| and satisfies some other conditions. Under certain restrictions on the perturbation c, …
