Type: article
Abstract: This paper investigates the existence of solutions for the following class of coupled systems of partial differential equations with an interface condition { - Δ u i = λ i a i ( x ) u i + b i ( x ) | u i | p i - 2 u i in Ω i , ∂ ν u i = γ ( u 2 - u 1 ) on Σ , ∂ η u 2 = 0 on Γ , \left\{\begin{aligned} \displaystyle{}{-}\Delta u_{i}&\disp
