We live in a world of resonances. The human environment is filled with natural and artificial resonators, ranging from musical instruments to complex devices such as lasers and body-imaging machines.

In this article, we consider the following problem { (−Δ) s u=α u + −β u − +f(u)+h inΩ u=0 on ℝ n \Ω, , where Ω ⊂ ℝn is a bounded domain with Lipschitz boundary, n > 2s, 0 < s < 1, (α, β) ∈ ℝ², ƒ : ℝ ...
